WinRAR

WinRAR 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.
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.
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<pwd> or -mes switches to suppress such prompts.

8. New -ep4<path> 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<path> switch sets the destination folder for 'x' and 'e'
extraction commands. Unlike <path_to_extract\> 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<size> switches specifying different sizes for different
volumes are now allowed also for ZIP archives:

WinRAR a -v100k -v200k -v300k arcname.zip

Previously multiple -v<size> switches were supported only for
RAR archives.

18. Switches -sl<size> and -sm<size> 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.
1. "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.

2. Added extraction of .zst archives starting from so called
skippable frame with user defined data. Previous beta versions
supported .zst archives only with standard frame in the beginning.

3. Improved the precision of extraction progress for RAR5 archives
with large recovery record.

4. Bugs fixed:

a) there was a memory leak when unpacking data in XZ format;

b) "Delete archive" extraction option failed to delete .zx## parts
of multipart .zipx archive;

c) an excessive trailing colon was displayed in "lt" command output
for numeric Unix owner and group information.
1. WinRAR icon is displayed on Windows 11 taskbar after invoking
WinRAR from Explorer context menu. There was no icon in previous
beta version in this case.

2. Archive information dialog includes the proper compression
dictionary size for ZIP Deflate64 and Implode compression methods.
Previously it was always 32 KB for them.

3. Bugs fixed:

a) WinRAR shell extension could crash in Windows 11;

b) restoring from tray did not correctly place WinRAR under other
opened windows in Windows 7;

c) "Cascaded context menus" option in "Settings" dialog was always
displayed as turned on, even if user turned it off earlier.
1. WinRAR can unpack contents of .zst and .zipx archives utilizing
Zstandard algortithm.

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. Windows XP is not supported anymore. Minimum required operating
system version is Windows Vista.

4. "Close" item is added to "When done" list on "Advanced" page of
archiving dialog. It closes WinRAR window, when archiving is done.

5. "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.

6. 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\

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'.

8. New -mes switch skips encrypted files when extracting or testing.

9. New -op<path> switch sets the destination folder for 'x' and 'e'
extraction commands. Unlike <path_to_extract\> command line parameter,
this switch also accepts paths without trailing path separator
character.

10. If 'p' command is used to print a file to stdout, informational

16. Multiple -v<size> switches specifying different sizes for different
volumes are now allowed also for ZIP archives:

from WinRAR "Settings/Compression".

21. "Rename" command selects the file name part up to the final dot.
Previously it selected the entire name.

22. If SFX archive sizes 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.

23. 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.

24. 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 (14.06.2021)

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<priority> 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 (12.04.2021)

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 <filename>"
or "Testing <filename>" 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.
