WinRAR - What's new in the latest version
Version 7.10 beta 1
1. "Settings/General" dialog page is split to "Settings/Interface"
and "Settings/System" pages. Dialog navigation uses vertical tabs
instead of horizontal.
2. WinRAR sets the dark interface mode if "Dark mode" option
in "Settings/Interface" is on. This option can enable or disable
the dark mode unconditionally or use Windows dark mode settings.
3. "Large memory pages" option in "Settings/System" dialog and -mlp
command line switch enable using 2 MB memory pages instead of
default 4 KB, when allocating large memory areas in RAR archive
format compression and extraction routines.
It allows to improve archiving and, in some cases, extraction speed.
Typically the performance gain is more significant for bigger
compression dictionaries and slower compression methods.
This feature requires "Lock pages in memory" privilege
and if it is missing, WinRAR proposes to assign it to the current
user account, making it available for other software too.
Windows restart is necessary to activate the newly assigned privilege.
4. "Zone value only" option in "Settings/Security" dialog controls
if archive Mark of the Web propagation includes only the security zone
value or all available fields.
While additional fields, such as a download location or IP address,
might help to identify a file source, they can be a privacy concern
if file is shared with other persons.
5. Switch -om[-|1][=list] controls Mark of the Web propagation
in WinRAR and console RAR command line mode.
6. Windows Vista and 32-bit Windows are not supported anymore.
WinRAR requires Windows 7 x64 or later.
Unlike WinRAR, 32-bit self-extracting modules are still provided
as a part of 64-bit installation package.
7. "Auto", "Always on" and "Disable" choices are now available
for "Delta compression" and "x86 executable compression" options
in "Advanced compression parameters" dialog.
To improve the compression speed, "Auto" applies these options
depending on the compression method, such as disabling them
for "Fastest" and "Fast" methods. Use "Always on" to enable them
for all methods.
8. Name of environment variable to store the default set of RAR switches
is changed from "RAR" to "RARINISWITCHES". It is rather typical
for batch scripts to use "RAR" environment variable name to store
RAR executable pathname, which led to the name conflict previously.
9. "Completion message title" and "Completion message text" options
on "Text" page of "Advanced SFX options" dialog allow to define
a custom message displayed on the successful completion of SFX archive
extraction.
This message can also be added with "TextDone" script command.
SFX logo and icon options are moved to the new "Logo and icon" page
of "Advanced SFX options" dialog. Dialog navigation uses vertical tabs
instead of horizontal.
10. Windows 11 context menu:
a) compression profiles in the new context menu are placed above
extraction commands, similarly to the legacy context menu;
b) separator lines are inserted between archive open, extraction
and archiving command groups.
11. When extracting a file with NTFS "Compressed" attribute,
this attribute is assigned in the beginning of file extraction.
Typically it reduces the extraction time compared to assigning it
after writing the file data.
12. When adding files to existing RAR archive, folders previously stored
in such archive are moved to a position after newly added files.
So folder timestamps are set after extracting all files and are not
modified when creating files inside of these folders.
13. Temporary file isn't created anymore for "rar ch -tl" command
if no archive modification switches like -rr or -z have been specified.
Modification time of newest archived file is set directly to original
archive file, without copying the archive data. It reduces disk write
and processing time.
14. If archive is truncated at recovery record or quick open information
service blocks, the additional message with truncated block type
is displayed after the standard "Unexpected end of archive".
15. Bugs fixed:
a) even though the long range search isn't used with -m1 "fastest"
compression method, switches -m1 -mcl+ or -m1 -mcl with 256MB
or larger compression dictionary still allocated memory required
for long range search algorithm;
b) if "Remove redundant folders from extraction path" option was on
when extracting a file from archive subfolder, clicking on ".."
in the file list afterwards displayed the folder with the archive
file instead of parent folder inside of archive;
c) if application was started from archive and created multiple files
with monotonically growing date, WinRAR could issue archive update
prompts for every created file instead of a single prompt.
Version 7.01
1. Bugs fixed:
a) updating an encrypted file in a solid RAR archive produced
a corrupt archive if updated file was the first in archive,
no password was specified when starting updating and file name
encryption in the updated archive wasn't enabled;
b) WinRAR 7.00 crashed after switching to "Flat folders view" mode
from archive subfolder;
c) switch -ep4 duplicated the specified path instead of excluding it
when extracting;
d) if archive created by Unix RAR version contained symlinks with
path separator characters in target paths, these characters could be
broken when modifying such archive with Windows RAR;
e) invalid file name was displayed in file rename and file execute
WinRAR error messages;
f) SFX "Shortcut" command failed to recognize empty parameters
defined like "Shortcut=D,"",folder", while correctly recognizing
such parameters without quote marks like "Shortcut=D,,folder";
g) volume reconstruction didn't work in WinRAR.exe if "rc" command
was specified with .rev file, such as "WinRAR rc arc.part1.rev".
Unlike RAR, WinRAR required to use only .rar file name here.
Version 7.00
1. Compression dictionary sizes larger than 1 GB are supported
for RAR archive format. Depending on the amount of physically
available memory, dictionary up to 64 GB can be selected.
Not power of 2 dictionary sizes can be specified for dictionaries
exceeding 4 GB. So we are not limited to 4, 8, 16, 32, 64 series
and can use values like 5 GB or 22 GB.
Archives with dictionaries exceeding 4 GB can be unpacked only
by WinRAR 7.0 or newer. 64-bit WinRAR version is needed to unpack
archives with dictionaries exceeding 1 GB.
Increasing the dictionary size can improve the compression ratio
for large files with distant repeated blocks, like virtual machine
disk images. It also can be efficient for sets of large similar files
in a solid archive, such as a collection of software ISO images
differing by version or localization.
2. WinRAR issues a prompt allowing to cancel or continue if dictionary
size in extracted RAR archive exceeds "Maximum dictionary size
allowed to extract" parameter in "Settings/Compression".
It is done to prevent the unexpected excessive memory allocation.
In the command line mode by default WinRAR refuses to unpack archives
with dictionary exceeding 4 GB. Use -md or -mdx to allow
unpacking dictionaries up to and including the specified size.
Unlike -md, -mdx is applied to extraction only and can be
added to RAR environment variable, not affecting archiving commands.
3. "Define dictionary sizes" dialog in "Settings/Compression" can be used
to customize dictionary sizes proposed in the drop down list associated
with "Dictionary size" field in "Archive name and parameters" dialog.
4. Alternate search algorithm, optimized to locate longer and more distant
repeated data blocks, can be used when creating RAR archives.
It helps to improve the compression ratio and sometimes speed
for redundant data like big text files.
It increases memory usage and might reduce the compression speed
for some types of data. It can be turned on or off with
"Long range search" options in "Advanced compression parameters" dialog
or with -mcl[+|-] switch. If "Auto" option is selected, WinRAR applies
the long range search depending on the compression method, dictionary
size and other parameters.
This algorithm is required for dictionaries exceeding 4 GB
and turning it off is ignored for such dictionaries.
5. Much slower and more exhaustive repeated data search and compression
algorithm can be enabled with "Exhaustive search" option
in "Advanced compression parameters" dialog or with -mcx switch.
It might provide the additional compression gain for some types of
redundant data, but at much lower compression speed.
Long range search is needed to implement this mode efficiently,
so the exhaustive search option activates it automatically.
Both long range and exhaustive search option do not affect
the compatibility of created archives. So if dictionary size
is in 128 KB - 4 GB range, archives created with these search options
can be unpacked by all WinRAR versions beginning from 5.0.
6. Maximum path length limit is increased from 2047 to 65535 characters.
7. Creating archives in RAR 4.x format isn't supported anymore.
Options and switches specific for this format are removed.
It doesn't affect RAR 4.x archives decompression, which is included
into WinRAR.
8. "Propagate Mark of the Web" option in "Settings/Security" dialog
controls assigning the archive Mark of the Web to extracted files.
It is possible to prohibit propagating, allow it for several
predefined file groups, for all files or for files matching user
defined file masks.
Mark of the Web is the security zone information added by Internet
browsers to downloaded files. It can be used by various software
for security purposes.
It is supported only by GUI WinRAR. Console RAR doesn't propagate
Mark of the Web regardless of this option.
9. "Attributes" column can be enabled in "Settings/File list/Columns".
It displays file attribute abbreviations, such as 'A' for "Archive"
and 'D' for directory.
If file attribute isn't among those recognized by WinRAR,
the numeric value of file attributes is also displayed.
This value uses hexadecimal format for Windows attributes
or octal format for Unix attributes.
10. "Benchmark" command allows to specify the exact number of threads
and copy results to clipboard. Information about WinRAR and Windows
versions, CPU and memory is added to benchmark window.
11. "Remove redundant folders from extraction path" option
in "Settings/Paths" is now applicable also to extraction commands
invoked from WinRAR user interface and to multiple archives
unpacked to separate folders. It removes a destination path
component, only if its name matches both the archive name and root
archived folder name, provided that there are no other folders
or files in archive root.
For example, it will remove one of "Pictures" in the destination path
if we unpack Pictures.rar containing the root "Pictures" folder
to "Pictures\" destination.
Previously it worked only for a single archive extracted from
context menu and didn't check if archived folder name matches
the last destination path component.
12. "Word wrap in comment" option in "Interface" options group
in "Settings/General" toggles the word wrap mode in archive comment
window.
13. Dictionary size data in archive information dialog is now available
for .bz2, .lz, .tar.bz2, .tar.gz, .tar.lz, .tar.zst archives.
14. Switch -ol- prohibits archiving and extracting symbolic links.
15. Switches -sl[u] and -sm[u] recognize [k|K|m|M|g|G|t|T]
size units for kilobytes, thousands of bytes, megabytes, millions
of bytes, gigabytes, billions of bytes, terabytes, trillions of bytes.
If unit character is 'b', 'B' or not present, bytes are assumed.
Previously these switches accepted bytes only.
16. SFX TempMode command accepts the optional @set:user parameter
allowing to modify temporary folder permissions, so only the current
user can access it. It prohibits a local user to replace files
in a temporary folder if SFX is started under another account.
It also can be enabled with "Restrict folder access" option
in "Advanced SFX options/Modes" dialog.
Some installers might fail to start in a folder created with
@set:user parameter.
17. File permissions and NTFS alternate streams are not saved for
hard link entries. They are saved only for the source file these
entries refer to. It allows to reduce the archive size, because
such file properties are automatically propagated to hard links
copies when extracting.
18. Keyboard shortcuts, such as Ctrl+A to select all files or Alt+E to
unpack found archives, are now functional in "Search results" window
also while search is still in progress. Previously they were available
only after completing search.
19. Switch -v[unit] recognizes 't' and 'T' as terabytes and
trillions of bytes for volume size units.
20. Warning is issued if leading '-' character is missing in a parameter
specified in "Additional switches" field of WinRAR archiving
and extraction dialogs. Also it is issued for parameters lacking '-'
in RAR environment variable and rar.ini file.
Previously such malformed parameters were ignored silently.
21. "Convert archives" command displays the smooth total operation progress.
Previously the total progress was updated abruptly after converting
an archive and was visible only when processing multiple archives.
22. Proper progress is displayed when compressing symbolic link targets.
23. "Integrate WinRAR into shell" option in WinRAR "Settings/Integration"
is grayed out if "Global\Integration=0" is present in winrar.ini file.
24. 64-bit WinRAR version uses 64-bit SFX modules by default.
64-bit SFX modules are needed to unpack archives with dictionaries
exceeding 1 GB.
32-bit modules are renamed to Default32.SFX, Zip32.SFX, WinCon32.SFX.
25. Maximum allowed dictionary size for archiving and extraction
can be specified in gigabytes in MaxDictA and MaxDictE variables
in "HKEY_CURRENT_USER\Software\WinRAR\Policy" Registry key.
If these variables are smaller than corresponding values defined
in WinRAR interface, they override interface values.
26. Console RAR filters out character 27 from screen output. It is done
for security reasons, because this character can be used to declare
ANSI escape control sequences in some terminal applications.
We are thankful to Siddharth Dushantha for bringing this issue
to our attention.
27. Bugs fixed:
a) it was possible to overwrite Mark of the Web, propagated from
archive to extracted files, and modify its security zone information
utilizing a specially crafted .rar archive.
We are thankful to Orange Tsai and NiNi from DEVCORE Research Team
working with Trend Micro Zero Day Initiative for letting us know
about this security issue.
Unlike WinRAR, unrar.dll library doesn't propagate the archive
Mark of the Web and leaves it to a caller application to assign it
to extracted files. So unrar.dll isn't affected by this issue;
b) "User defined archive extensions" field in "Settings/Integration"
was not saved if winrar.ini was used to store settings
and WinRAR was started under non-administrator user account.
Version 6.24
1. Bugs fixed:
a) WinRAR and UnRAR.dll extraction command dereferenced a null pointer
and crashed when processing a zero length archive name
in the archive metadata stored with -am switch.
We are thankful to Radoslaw Madej from Check Point software
for reporting this issue;
b) WinRAR and UnRAR.dll extraction command overwrote extracted file
data with contents of ::$DATA NTFS alternate data stream,
if such stream was present in the archive. In this case
unpacked data size and checksum could mismatch file size
and checksum displayed in WinRAR file list. It didn't affect
file name and type, which were displayed properly.
We are thankful to Ata Hakcil for reporting this issue.
Version 6.23
1. Added extraction of XZ archives utilizing ARM64 filter.
2. Rar$LS* temporary files, created when extracting or testing multiple
archives from Windows context menu, are now deleted immediately.
Previously they were deleted only on next WinRAR runs and only
if they were at least 1 hour old.
3. Bugs fixed:
a) a security issue involving out of bounds write is fixed
in RAR4 recovery volumes processing code.
We are thankful to goodbyeselene working with Trend Micro Zero Day
Initiative for letting us know about this bug;
b) WinRAR could start a wrong file after a user double clicked
an item in a specially crafted archive.
We are thankful to Andrey Polovinkin from Group-IB Threat
Intelligence unit for letting us know about this bug;
c) if both NTFS and Unix time extra fields were available for a file
in ZIP archive, extraction command ignored the second extra field
even if it provided more time fields than first one;
d) interface themes were applied to archive icons even if
"Apply to archive icons" option in "Organize themes" dialog
was turned off.
Version 6.22
1. Bugs fixed:
a) extracting individual files from solid archives created by
RAR versions older than 2.0, could fail in WinRAR 6.20 and 6.21.
It didn't affect extracting the entire archive, which was performed
correctly;
b) files in Unix ARJ archives could be erroneously displayed as folders
in WinRAR file list;
c) "Display files in Explorer" extraction option was ignored
if "When done: Close WinRAR" option was also set and archive
was opened in WinRAR before extracting;
d) file size value in the internal viewer status bar didn't include
the byte order mask field, displaying a smaller than actual size
for Unicode files.
Version 6.21
1. Both file and folder modification timestamps are restored
when unpacking TAR and TAR based archives like tar.gz and tar.bz2.
Previously only file modification timestamps were set
for these archive formats.
2. Added decompression of .tar.zst archives with dictionary
exceeding 128 MB. WinRAR 6.20 allowed such dictionary for .zst,
but not for .tar.zst.
3. Switches -ed and -e+d are also supported by ZIP archives.
Previously they worked only for RAR archives.
4. Bugs fixed:
a) if unencrypted file was stored after encrypted in the same
RAR archive and both files had been unpacked in the same extraction
command, WinRAR 6.20 failed to unpack the unencrypted file;
b) in some cases a wrong detailed reason of file open error could be
displayed in the second line of open error message.
Version 6.20
1. If "Autodetect passwords" option in "Organizer passwords" dialog
is enabled and password matching a processing archive is present
among saved passwords, it is applied automatically. This option
is applicable only for archives in RAR 5.0 and ZIP formats,
which allow to verify the password validity quickly.
There is a minor chance of incorrect password detection
for ZIP archives if stored passwords do not include a proper one.
If encrypted ZIP archive extraction fails, you can try to disable
this option, repeat extraction and enter a valid password manually.
2. If extraction command involves only a part of files in RAR archive,
the additional archive analysis is performed when starting extraction.
It helps to properly unpack file references even if reference source
is not selected. It works for most of RAR archives except for volumes
on multiple removable media and archives containing a very large
number of references.
Also in some cases such analysis may help to optimize the amount
of processing data when extracting individual files from
semi-solid archives created with -s and -se switches.
3. "Save original archive name and time" option on "Options" page
of archiving dialog allows to save the original archive name
and creation time. If archive includes such saved name and time,
they are displayed on "Info" page of "Show information" command
and can be restored on "Options" page of same command.
Restoring involves renaming an archive to original name and setting
the saved time as the archive creation and modification time.
Switch -ams or just -am together with archive modification commands
can be used to save the archive name and time in the command line mode.
These saved parameters are displayed in header of "l" and "v" commands
output and can be restored with -amr switch combined with "ch" command,
such as "rar ch -amr arc.rar". If -amr is specified, "ch" ignores
other archive modification switches.
4. Faster RAR5 compression of poorly compressible data on modern CPUs
with 8 or more execution threads. This applies to all methods
except "Fastest", which performance remains the same.
5. "Repair" command efficiency is improved for shuffled data blocks
in recovery record protected RAR5 archives.
6. If file size has grown after archiving when creating non-solid
RAR volumes, such file is stored without compression regardless of
volume number, provided that file isn't split between volumes.
Previously it worked only for files in the first volume.
7. Added decompression of .zipx archives containing file references,
provided that both reference source and target are selected
and reference source precedes the target inside of archive.
Typically, if .zipx archive includes file references, it is necessary
to unpack the entire archive to extract references successfully.
8. Added decompression of .zst long range mode archives with dictionary
exceeding 128 MB. Previously it was possible to decompress them only
if dictionary was 128 MB or less.
9. If "Turn PC off", "Hibernate", "Sleep" or "Restart PC" archiving
options are enabled in WinRAR, a prompt to confirm or cancel
such power management action is displayed directly before starting it.
If no selection was made by user for 30 seconds, the proposed action
is confirmed and started automatically.
This prompt is also displayed for -ioff switch in WinRAR command line,
but not in console RAR command line.
10. Context menu in WinRAR file list provides "Open in internal viewer"
command for archive files. It can be helpful if you wish to view
the archive raw data in internal viewer. For example, to read
an email archive with UUE attachments included.
Usual "View" command always displays the archive contents.
If file is recognized as UUE archive, "View" would show UUE attachments.
11. Recovery record size is displayed on "Archive" page of file properties
invoked from Explorer context menu for archives in RAR5 format.
Previously there was only "Present" instead of exact size
for RAR5 archives.
12. When archiving from stdin with -si switch, RAR displays the current
amount of read bytes as the progress indicator.
13. If wrong password is specified when adding files to encrypted
solid RAR5 archive, a password will be requested again.
Previous versions cancelled archiving in this case.
14. If both options "Test archived files" and "Clear attribute "Archive"
after compressing" or their command line -t -ac equivalents are
enabled when archiving, "Archive" attribute will be cleared only
if test was completed successfully. Previously it was cleared even
when test reported errors.
15. NoDrives value containing the bit mask to hide drives can be now
read from "HKEY_CURRENT_USER\Software\WinRAR\Policy" Registry key,
which allows to include it to winrar.ini if necessary.
Its "Software\Microsoft\Windows\CurrentVersion\Policies" locations
in HKEY_CURRENT_USER and HKEY_LOCAL_MACHINE are also supported.
Previously only "Software\Microsoft\Windows\CurrentVersion\Policies"
in HKEY_CURRENT_USER was recognized.
16. Bugs fixed:
a) archive modification commands could fail for some ZIP archives
with file comments;
b) fixed a memory leak when reading contents of .tar.bz2 archives;
c) if source and resulting archive format is the same, the archive
conversion command didn't set the original archive time
to a newly created archive even if "Original archive time" option
was selected in archiving parameters;
d) if "Merge volumes contents" option in "Settings/File list" was
turned on, the folder packed size in WinRAR file list could be
less than expected when browsing a multivolume archive contents.
It didn't include the packed size of file parts continuing from
previous volume into calculation;
e) even if "Set file security" extraction option was turned off
by default, extraction commands in Explorer context menu still
attempted to restore NTFS file security data;
f) WinRAR could read data beyond the end of buffer and crash
when unpacking files from specially crafted ZIP archive.
We are thankful to Bakker working with Trend Micro Zero Day
Initiative for letting us know about this bug.
Version 6.11
1. Added support for Gz archives with large archive comments.
Previously the extraction command failed to unpack gz archives
if comment size exceeded 16 KB.
2. Archive comments in gz archives are displayed in the comment window
and recognized by "Show information" command. Large comments are
shown partially.
Previous versions didn't display Gzip comments.
3. Reserved device names followed by file extension, such as aux.txt,
are extracted as is in Windows 11 even without "Allow potentially
incompatible names" option or -oni command line switch.
Unlike previous Windows versions, Windows 11 treats such names
as usual files.
Device names without extension, such as aux, still require these
options to be unpacked as is regardless of Windows version.
4. Switch -mes can be also used to suppress the password prompt
and abort when adding files to encrypted solid archive.
5. Additional measures to prevent extracting insecure links are
implemented.
6. Bugs fixed:
a) if password exceeding 127 characters was entered when unpacking
an encrypted archive with console RAR, text after 127th character
could be erroneously recognized as user's input by different
prompts issued later;
b) wrong archived file time could be displayed in overwrite prompt
when extracting a file from ZIP archive. It happened if such
archive included extended file times and was created in another
time zone. It didn't affect the actual file time, which was set
properly upon extraction.
Version 6.10
1. WinRAR can unpack contents of .zst and .zipx archives utilizing
Zstandard algorithm.
2. Added support of Windows 11 Explorer context menus.
Beginning from Windows 11, an application can add only a single top
level command or submenu to Explorer context menu.
If "Cascaded context menus" in "Integration settings" dialog is on,
this single item is a submenu storing all necessary WinRAR commands.
If this option is off, only one extraction command for archives
and one archiving command for usual files are available.
You can select these commands with "Context menu items..." button
in "Integration settings" dialog.
3. "Legacy context menus" option in "Settings/Integration" dialog
can be used in Windows 11 if WinRAR commands are missing in
"Show more options" Windows legacy context menu or in context menus
of third party file managers. If WinRAR commands are already present
here, keep "Legacy context menus" option turned off to prevent
duplicating them.
This option is not available in Windows 10 and older.
4. Windows XP is not supported anymore. Minimum required operating
system version is Windows Vista.
5. "Close" item is added to "When done" list on "Advanced" page of
archiving dialog. It closes WinRAR window, when archiving is done.
6. "When done" list is added to "Options" page of extraction dialog.
It allows to select an action like turning a computer off
or closing WinRAR after completing extraction.
7. Switch -si can be used when extracting or testing to read archive
data from stdin, such as:
type docs.rar | rar x -si -o+ -pmypwd dummy docs\
Even though the archive name is ignored with this switch,
an arbitrary dummy archive name has to specified in the command line.
Operations requiring backward seeks are unavailable in this mode.
It includes displaying archive comments, testing the recovery record,
utilizing the quick open information, processing multivolume archives.
Prompts requiring user interaction are not allowed.
Use -o[+|-|r], -p or -mes switches to suppress such prompts.
8. New -ep4 switch excludes the path prefix when archiving
or extracting if this path is found in the beginning of archived name.
Path is compared with names already prepared to store in archive,
without drive letters and leading path separators. For example:
rar a -ep4texts\books archive c:\texts\books\technical
removes "text\books" from archived names, so they start
from 'technical'.
9. New -mes switch skips encrypted files when extracting or testing.
It replaces the former -p- switch.
10. New -op switch sets the destination folder for 'x' and 'e'
extraction commands. Unlike command line parameter,
this switch also accepts paths without trailing path separator
character.
11. If 'p' command is used to print a file to stdout, informational
messages are suppressed automatically to prevent them mixing
with file data.
12. "Generate archive name by mask" option and switch -ag treat only
first two 'M' characters after 'H' as minutes. Previously any
amount of such characters was considered as minutes.
It makes possible to place the time field before the date,
like -agHHMM-DDMMYY. Previous versions considered all 'M'
in this string as minutes.
13. Maximum allowed size of RAR5 recovery record is increased to 1000%
of protected data size. Maximum number of RAR5 recovery volumes
can be 10 times larger than protected RAR volumes.
Previous WinRAR versions are not able to use the recovery record
to repair broken archives if recovery record size exceeds 99%.
Similarly, previous versions cannot use recovery volumes
if their number is equal or larger than number of RAR volumes.
14. Warning is issued if entered password exceeds the allowed limit
of 127 characters and is truncated. Previously such passwords
had been truncated silently.
15. If archive includes reserved device names, the underscore character
is inserted in the beginning of such names when extracting.
For example, aux.txt is converted to _aux.txt. It is done to prevent
compatibility problems with software unable to process such names.
You can use "Allow potentially incompatible names" option
in "Advanced" part of extraction dialog or command line -oni switch
to avoid this conversion.
16. WinRAR attempts to reset the file cache before testing an archive.
It helps to verify actual data written to disk instead of reading
a cached copy.
17. Multiple -v switches specifying different sizes for different
volumes are now allowed also for ZIP archives:
WinRAR a -v100k -v200k -v300k arcname.zip
Previously multiple -v switches were supported only for
RAR archives.
18. Switches -sl and -sm can be used in WinRAR.exe command
line mode when extracting archives in any supported formats,
provided that such archive includes unpacked file sizes.
Previously these switches could filter files by size only in RAR
and ZIP archives.
19. Newer folder selection dialog is invoked when pressing "Browse" button
in WinRAR "Settings/Paths" page, "Repair" and "Convert" commands,
also as in few other similar places. Previously a simpler XP style
folder selection dialog was opened.
20. When restoring from tray after completing an operation,
WinRAR window is positioned under other opened windows,
to not interfere with current user activities.
21. "650 MB CD" is removed and "2 GB volumes" is added to the list of
predefined volume sizes in "Define volume sizes" dialog invoked
from WinRAR "Settings/Compression".
22. "Rename" command selects the file name part up to the final dot.
Previously it selected the entire name.
23. If SFX archive size exceeds 4 GB, an error message is issued
during compression, immediately after exceeding this threshold.
Previously this error was reported only after completing compression.
Executables of such size cannot be started by Windows.
24. Command line -en switch is not supported anymore.
It created RAR4 archives without the end of archive record.
End of archive record permits to gracefully skip external data
like digital signatures.
25. Bugs fixed:
a) when editing a file inside of .rar or .zip archive,
WinRAR created a new SFX archive instead of updating an existing
archive if "Create SFX archive" option was set in the default
compression profile;
b) the total progress could be displayed incorrectly when using
-oi, -f, -u switches or appropriate GUI options;
c) "Find files" command with "Use all tables" option and command line
"it" commands failed to find strings in UTF-16 encoding.
Version 6.02
1. ZIP SFX module refuses to process SFX commands stored in archive
comment if such comment is resided after beginning of Authenticode
digital signature. It is done to prevent possible attacks with
inclusion of ZIP archive into the signature body.
We already prohibited extracting contents of such malformed archives
in WinRAR 6.01.
We are thankful to Jacob Thompson - Mandiant Advantage Labs
for reporting this issue.
2. WinRAR uses https instead of http in the web notifier window,
home page and themes links. It also implements additional checks
within the web notifier. This is done to prevent a malicious web page
from executing existing files on a user's computer. Such attack
is only possible if the intruder has managed to spoof or otherwise
control user's DNS records. Some other factors are also involved
in limiting the practical application of this attack.
We would like to express our gratitude to Igor Sak-Sakovskiy
for bringing this issue to our attention.
3. Where appropriate, SFX archive displays the additional line
with detailed error information provided by operating system.
For example, previously such archive would display "Cannot create file"
message alone. Now this message is followed by a detailed reason
like access denied or file being used by another process.
In the past this extended error information was available in WinRAR,
but not in SFX archives.
4. Switch -idn hides archived names also in 'v' and 'l' commands.
It can be useful if only the archive type or total information
is needed.
5. If -ibck -ri switches are used together, WinRAR process
sets the priority specified in -ri switch. Previous versions ignored
-ri and set the priority to low in the presence of -ibck switch.
6. When using "File/Change drive" command, WinRAR saves the last folder
of previous drive and restores it if that drive is selected again
later.
7. Name of unpacking file is now included into WinRAR incorrect password
warning for RAR5 archives. It can be helpful when unpacking
a non-solid archive containing files encrypted with different passwords.
8. Bugs fixed:
a) "Convert archives" command issued erroneous "The specified password
is incorrect" message after succesfully converting RAR archive
with encrypted file names if new password was set and archive
was opened in WinRAR shell;
b) if command progress window was resized up and then quickly resized
down to original dimensions, window contents could be positioned
incorrectly.
Version 6.01
1. Ctrl+A keyboard shortcut selects the entire text in WinRAR comment
window.
2. If -idn switch is used together with -t or -df in console RAR
when archiving, it additionally disables "Deleting "
or "Testing " messages, normally issued by these switches.
Also -idn disables folder creation messages when extracting
a file to non-existing folder.
3. WinRAR and ZIP SFX module refuse to extract contents of ZIP SFX
archives if ZIP central directory is resided after beginning
of Authenticode digital signature. It is done to prevent possible
attacks with inclusion of ZIP archive into signature body.
4. Bugs fixed:
a) "Convert archives" command could incorrectly convert Unicode
comments in RAR archives.
b) if two archive information windows had been opened from Explorer
context menu, the compression ratio bar in the first window
could erroneously display a value for second archive.
It did not affect the ratio and other text details at the right
of window. Only the vertical bar at the left could be updated
to a wrong value;
c) if "Wait if other WinRAR copies are active" option was enabled
in extraction dialog, "Waiting for another WinRAR copy" title
was not set in command progress window while waiting;
d) when extracting a symbolic link, previous versions did not
overwrite existing symbolic links even if user requested it
in overwrite prompt.
Version 6.00
1. "Ignore" and "Ignore All" options are added to read error prompt.
"Ignore" allows to continue processing with already read file part
only and "Ignore All" does it for all future read errors.
For example, if you archive a file, which portion is locked by another
process, and if "Ignore" is selected in read error prompt,
only a part of file preceding the unreadable region will be saved
into archive.
It can help to avoid interrupting lengthy archiving operations,
though be aware that files archived with "Ignore" are incomplete.
If switch -y is specified, "Ignore" is applied to all files by default.
Previously available "Retry" and "Quit" options are still present
in read error prompt as well.
2. Exit code 12 is returned in the command line mode in case of read errors.
This code is returned for all options in the read error prompt,
including a newly introduced "Ignore" option.
Previously more common fatal error code 2 was returned for read errors.
3. If several archives are selected, "Extract archives to" option group
in "Options" page of extraction dialog can be used to place extracted
files to specified destination folder, to separate subfolders
in destination folder, to separate subfolders in archive folders
and directly to archive folders.
It replaces "Extract archives to subfolders" option and available
only if multiple archives are selected.
4. New -ad2 switch places extracted files directly to archive's own folder.
Unlike -ad1, it does not create a separate subfolder for each unpacked
archive.
5. "Additional switches" option in "Options" page of archiving
and extraction dialogs allows to specify WinRAR command line switches.
It might be useful if there is no option in WinRAR graphical interface
matching a switch.
Use this feature only if you are familiar with WinRAR command line
syntax and clearly understand what specified switches are intended for.
6. Compression parameters in "Benchmark" command are changed to
32 MB dictionary and "Normal" method. They match RAR5 default mode
and more suitable to estimate the typical performance of recent
WinRAR versions than former 4 MB "Best" intended for RAR4 format.
Latest "Benchmark" results cannot be compared with previous versions
directly. New parameters set produces different values, likely lower
because of eight times larger dictionary size.
7. When unpacking a part of files from solid volume set,
WinRAR attempts to skip volumes in the beginning and start
extraction from volume closest to specified file and with reset
solid statistics.
By default WinRAR resets the solid statistics in the beginning
of large enough solid volumes where possible. For such volumes
extracting a part of files from the middle of volume set can be
faster now.
It does not affect performance when all archived files are unpacked.
8. Previously WinRAR automatically resorted to extracting from
first volume, when user started extraction from non-first volume
and first volume was available. Now WinRAR does so only if all volumes
between first and specified are also available.
9. Warning is issued when closing WinRAR if one or more archived files
had been modified by external apps, but failed to be saved back to
archive, because an external app still locks them. Such warning
includes the list of modified files and proposes to quit immediately
and lose changes or return to WinRAR and close an editor app.
Previous versions issued a similar warning while editing a file,
but did not remind it again when quitting.
10. "Move to Recycle Bin" option in "Delete archive" options group
of extraction dialog places deleted archives to Recycle Bin
instead of deleting them permanently.
11. New "Clear history..." command in "Options" menu allows to remove
names of recently opened archives in "File" menu and clear drop down
lists with previously entered values in dialogs. For example,
these values include archive names in archiving dialog
and destination paths in extraction dialog.
12. "File time" options in "Advanced" part of extraction dialog are
now available for 7z archives. Additionally to modification time,
WinRAR can set creation and last access time when unpacking such
archives.
13. ""New" submenu items" options group is added to
"Settings/Integration/Context menu items..." dialog. You can use
these options to remove "WinRAR archive" and "WinRAR ZIP archive"
entries in "New" submenu of Windows context menu.
New state of these option is applied only after you press "OK"
both in "Context menu items" and its parent "Settings" dialog.
14. , and commands can be inserted before the program
name in SFX "Setup" command to run a program in maximized,
minimized or hidden window. For example:
Setup=setup.exe
15. It is possible to specify an additional high resolution logo
for SFX module. If such logo is present, SFX module scales
and displays it in high DPI Windows mode, providing the better visible
quality compared to resizing the standard logo.
Use "High resolution SFX logo" in "Advanced SFX options" dialog
to define such logo. In command line mode add second -iimg switch
to set the high resolution logo.
Recommended size of high resolution logo PNG file is 186x604 pixels.
16. If archive currently opened in WinRAR shell was deleted or moved
by another program, WinRAR displays "Inaccessible" before archive name
in the window title. Also it flashes the window caption and taskbar
button.
17. "Total information" option in "Report" dialog is renamed to
"Headers and totals". Now it also adds headers of report columns
additionally to total information about listed files and archives.
18. If archive processing is started from Windows context menu
in multiple monitor system, WinRAR operation progress and dialogs
use the monitor with context menu.
While basic multiple monitor support was present in previous versions
shell extension for mouse driven commands, now it is extended to
operations initiated from keyboard and to dropping files to archives.
19. New -imon switch allows to select a monitor to display
WinRAR operation progress and dialogs in the command line mode.
Use -imon1 for primary and -imon2 for secondary monitor.
For example, "WinRAR x -imon2 arcname" will start extraction
on secondary monitor.
It works only in the command line mode and does not affect
interactive WinRAR graphical inteface also as console RAR.
20. Switch -idn hides archived names output in archiving, extraction
and some other commands in console RAR. Other messages and total
percentage are not affected.
You can use this switch to reduce visual clutter and console output
overhead when archiving or extracting a lot of small files.
Minor visual artifacts, such as percentage indicator overwriting
few last characters of error messages, are possible with -idn.
21. Former "-im - show more information" switch is changed to
"-idv - display verbose output" for consistency with console RAR
-id[c,d,p,q] message control options and avoid a potential name
conflict with newer -imon switch.
While WinRAR still recognizes both -im and -idv, in the future
-im support can be dropped.
22. It is allowed to add an optional %arcname% variable to compression
profile name. Such variable will be replaced with actual archive name.
It might be convenient when using with "Add to context menu" profile
option. For example, you can create ZIP compression profile
and set its name to "Add to %arcname%", to display it with actual
ZIP archive name in context menu.
23. Ctrl+C and Ctrl+Ins keyboard shortcuts can be used
in "Diagnostic messages" window to copy contents to clipboard.
24. More text is allowed in tray icon hint before a lengthy text
is truncated. Also such text is now truncated in the middle of string,
so both command type and completion percentage are still visible.
25. In case of clean install, if previous version compression profiles
are not present, "Files to store without compression" field
in newly created predefined compression profiles is set to:
*.rar *.zip *.cab *.7z *.ace *.arj *.bz2 *.gz *.lha *.lzh
*.taz *.tgz *.xz *.txz
You can change this field and save a modified value to compression
profile later.
Previous versions set this field to blank for clean install.
26. Destination path history in extraction dialog treats paths like
'folder' and 'folder\' as the same path and displays only 'folder'
entry. Previously they occupied two entries in the history.
27. "Enable Itanium executable compression" GUI option and -mci command
line switch are removed. Optimized compression of Itanium executables
is not supported anymore. WinRAR still can decompress already existing
archives utilizing Itanium executable compression.
28. Bugs fixed:
a) "Lock", "Comment" and "Protect" commands could not be applied
to several archives selected in WinRAR file list at once;
b) SFX archive process did not terminate after completing
extraction in Windows 10 if archive comment included "Setup"
and "SetupCode" commands, did not include "TempMode" command
and setup program was running for more than 8 minutes;
c) compression profiles with quote character in profile name
could not be invoked from Explorer context menu.
