WinRAR Latest Updates
WinRAR - What's new in the latest version 4.0
Version 4.00

1. RAR decompression speed is improved. Depending on data type, decompression can be up to 30% faster than in previous versions.

Both the general RAR algorithm and most of special RAR multimedia methods benefit from this improvement. The only module of RAR algorithm, which is not affected, is "Text compression" method.

2. Changes in ISO support:

a) UDF support is upgraded to UDF 2.50 revision. It makes possible to unpack most of Blu-ray ISO files;

b) when browsing UDF ISO file, UDF revision number is displayed after the "UDF" format name in WinRAR address bar and in archive information dialog;

c) WinRAR sets the folder modification date when unpacking folders stored in UDF and ISO9660 files.

3. Changes in password dialog:

a) WinRAR uses the same format of password dialog both when archiving and extracting, so "Show password" option is available also when extracting;

b) "Organize passwords..." button in password dialog provides access to password organizer interface, where you can specify
your frequently used passwords. You will be able to access these saved passwords using the drop down list or autocomplete feature in password dialog.

It is important to know that saved passwords are not encrypted and anybody having access to your computer can view them.
Use "Organize passwords" feature only if your computer is protected from unauthorized access;

c) "Use for all archives" option is available in password dialog when unpacking several archives at once. You can utilize it
to apply an entered password to all archives.

If you use this option with an empty password, WinRAR will skip all encrypted archives;

d) Unlike previous versions, the password from default compression profile is not used for extraction.

If you wish to use the same password for all extracting archives, press "Organize passwords..." button in the password dialog
and define a new password entry, specifying "*" file mask in "Select for archives" field.

4. In Windows 7 WinRAR will display the total operation progress also on WinRAR icon on Windows taskbar. You can disable it using "Taskbar progress bar" option on "General" page of WinRAR settings.

5. Numerous Unicode support improvements allow to process non-English file names more smoothly. These improvements include:

a) better Unicode handling in WinRAR in "Rename", "Convert", "Find" and other commands, in folder tree panel, in password
request dialog and in many other parts of WinRAR interface;

b) correctly displayed Unicode names in WinRAR items in Explorer context menus;

c) Unicode support in .lng files, making WinRAR localization possible for Unicode only languages.

6. Changes in -x switch syntax. Now you can specify a wildcard exclusion mask for folders. Such mask must have the trailing '\' character, like -x*tmp*\ or -x*\temp\

7. New "Extract relative paths" option in "Advanced" part of extraction dialog. If you browse some archive subfolder in WinRAR shell and enable "Extract relative paths" option, the path part up to and including the current subfolder will be removed from extracted file paths.

For example, if you are inside of "Backup\MyData" archive folder and extract "Images" folder, it will be extracted as "Images",
not as "Backup\MyData\Images".

This option is the new default extraction mode, but you can change the default back to WinRAR 3.x style. Just select "Extract full paths" and then press "Save settings" in "General" part of extraction dialog.

8. Windows 98, Windows Me and Windows NT are not supported by WinRAR and WinRAR self-extracting modules anymore. Minimum Windows version required for WinRAR 4.0 is Windows 2000.

If you need to run WinRAR on older Windows, you can download previous WinRAR versions from ftp://ftp.rarlab.com/rar

9. If TAR, TAR.GZ or TAR.BZ2 archive contains symbolic or hard links and if destination file system is NTFS, WinRAR will create these links when unpacking such archive. WinRAR will create symbolic links as symbolic and hard links as hard in Windows Vista and newer and it will create all links as hard in older Windows.

If destination file system is FAT32 or any other not supporting file links, WinRAR will skip links when unpacking TAR, TAR.GZ
and TAR.BZ2 archives.

10. Recovery volume processing involves less disk seek operations resulting in higher performance.

11. You can select Windows 7 library in tree panel in extraction dialog and WinRAR will use its default save location as the destination path.

12. "Report" command allows to select HTML, Unicode text and usual text as output format for report file. Unlike previous WinRAR versions, now WinRAR preservers Unicode characters in reports when using HTML or Unicode text format. So non-English characters in file names will be displayed properly in such reports.

13. Message list in GUI SFX archives displays only operation status and error messages. It does not contain names of all extracted files anymore. This change improves the speed and reduces memory requirements for SFX archives containing a large number of files. Also it makes easier to locate error messages, because they are not hidden among extracted file names.

14. GUI SFX archives display "Extract" button instead of "Install" if no "Setup" or "Presetup" commands are present in the archive comment. If you prefer "Install" button, but do not need to execute any setup programs, you can add "Setup=<>" command.

15. WinRAR displays the current percent above the operation progress bar when repairing an archive containing the recovery record and when processing recovery volumes.

16. WinRAR limits the maximum possible volume size to 4 GB minus 1 byte when creating RAR volumes on a disk with FAT or FAT32 file system in volume size autodetecting mode. These file systems do not support 4 GB and larger files.

17. If "Wait if other WinRAR copies are active" option is enabled and WinRAR waits for another copy, you can press "Continue" button in command progress window to force WinRAR to stop waiting. So now "Continue" button allows to override the state of
"Wait if other WinRAR copies are active" option for current operation.

18. WinRAR displays one password request instead of two, when saving an encrypted file back to RAR or ZIP archive after modifying it in some external editor. Previous WinRAR versions usually requested the password twice, both when extracting the original file and archiving its modified copy. Only RAR archives with encrypted file names were processed with the single password prompt.

19. New error code 10 ("no files") is added to list of error codes returned in command line mode by RAR and WinRAR. This new code can be returned by archive, extract, delete and repair commands. It means that RAR did not find any files matched the specified file or archive mask.

20. File name area in file overwrite dialog occupies several lines now. It makes possible to display much longer names.

21. Now switch -ep3 converts not only disk letters, but also UNC paths. So \\server\share will be converted to __server\share when archiving and restored to the original \\server\share when extracting with -ep3.

22. New "Background extraction" option in "Advanced" part of extraction dialog places WinRAR into background, when extracting files. You can save its default state with "Save settings" button in "General" part of extraction dialog, just like for other extraction options.

"Background archiving" option from the default compression profile does not affect the extraction behavior anymore.

23. "Mode..." button in operation progress window is enabled also when extracting or testing archives. It provides access to
"Command parameters" dialog, where you can set "Turn PC off when done" option for extraction and test operations.

Previously this dialog was accessible only when archiving.

24. Bugs fixed:

a) renaming a file in archive could also rename all other files with the same name in other folders of the same archive;

b) previous versions displayed the wrong total packed size in "Info" command for multivolume CAB archives;

c) in ZIP archives 'U' (update) and 'F' (fresh) commands could erroneously update even files not specified in the command line.
It happened only for files in current folder which names matched files in ZIP archive. This bug was not present in usual 'A' (add)
archiving mode.
WinRAR - What's new in the latest version 3.93

Version 3.93

1. Bugs fixed:

a) in WinRAR 3.92 -xd:\path\folder switch could also exclude folders, which path does not match the path specified in the switch
and only the folder name is the same as specified;
b) switches -y -or did not work correctly together. Switch -or was ignored in presence of -y.


Version 3.92

1. If you start WinRAR command from Explorer context menu in multiple monitor configuration, the command dialog will be displayed on the same monitor as context menu. In previous versions it was always displayed on primary monitor.

2. WinRAR "Compress and email..." context menu command adds the archive name to email subject. Previous versions left the subject blank.

3. In RAR 3.91 -x switch could also exclude folders from archiving even if mask contained wilcard characters and did not contain a path. For example, -x*. excluded all those folders, which do not have the extension in the name. Now -x switch uses RAR 3.80 approach for masks without path, excluding folders only if mask does not contain wildcards and matches the folder name exactly.

4. Bugs fixed:

a) WinRAR 3.91 reported the incorrect "Unexpected end of archive" error, when opening an empty ZIP archive created with
"New WinRAR ZIP archive" context menu command;

b) if "Delete archive" option was enabled when unpacking several ZIP archives and if one of archives was damaged, WinRAR did not delete archives after the damaged one, even if they were unpacked successfully;

c) if file matched two different masks in RarFiles.lst, WinRAR could select the last match. Normally, if neither of masks is a subset of another, the first match must be chosen.

Version 3.91

1. This version can decompress 7-Zip archives created with LZMA2 algorithm.

2. Now a password is requested only once when unpacking 7z archives with encrypted file names from context menu. WinRAR 3.90 asked it twice.

3. This version can unpack tar.bz2 archives consisting of several smaller bz2 streams merged together. Previous versions unpacked only the first nested bz2 stream in such composite archive.

4. WinRAR displays CRC32 of files inside of usual .gz (not .tar.gz) archives. Previous versions left this field blank for GZIP files.

5. Bugs fixed:

a) WinRAR 3.90 displayed "Save" button instead of "Open" or "OK" in "Find archive" dialog ("Open archive" command in "File" menu and "Browse..." command in archiving dialog);

b) WinRAR could display incorrect file names when browsing malformed ZIP archives;

c) WinRAR 3.90 failed to decompress LZH archives created with "-lh7-" algorithm;

d) WinRAR 3.90 could fail to delete a part of files after archiving if delete to Recycle Bin was enabled. This bug was present
when working in Windows XP, but not in Windows Vista and Windows 7;

e) when unpacking ISO file using WinRAR "Extract files..." command in Explorer context menu, WinRAR could unpack same archived files twice during the same operation. It displayed the overwrite prompt when unpacking files for the second time;

f) hexadecimal search in WinRAR 3.90 "Find" command and console RAR "ih" command failed to find matches if first byte in search string was greater than 127.

WinRAR - What's new in the latest version 3.90

1. WinRAR version for Windows x64 is available. If you use Windows x64, it is strongly recommended to install 64 bit WinRAR version. It provides a higher performance and better shell integration than 32 bit version.

2. RAR compression speed is improved for multi-core and multi-CPU systems. This improvement is most noticeable in Windows Vista and Windows 7 operating systems.

what's new3. "Remove duplicate folders from extraction path" option in "Settings/Compression" dialog is replaced by more universal "Remove redundant folders from extraction path" option. This option will eliminate redundant archive name based folders from extraction path if you unpack an archive with "Extract to DestName\" context menu command and if archive root folder contains only one folder and no files.

what's new4. Changes in "Extraction path and options" dialog:

a) "New folder" button creates a new subfolder in currently selected folder;

b) F2 key renames a selected folder in the folders tree;

c) F5 key updated the tree pane contents;

d) Del key removes a selected folder in the folders tree.

what's new5. You can enable "Show seconds" option in "Settings/File list" dialog if you wish to see seconds in file dates in file list in WinRAR shell.

what's new6. "Where to check for SFX archives" options group in "Settings/Integration/Context menus items" dialog lets you to control processing of SFX archives in context menus. For example, if you frequently right click ".exe" files on slow network disks, you can turn off "Network disks" options to minimize the delay before displaying the context menu.

what's new7. If you sort files by name in the file list in WinRAR shell, WinRAR will use the new logical file name sorting, same as in Windows Explorer, considering digits in file names by their numerical value. So files will be sorted as 1.txt, 2.txt, 10.txt instead of previous 1.txt, 10.txt, 2.txt. This new sort behavior is available in Windows XP Service Pack 2 and newer.

what's new8. Ctrl+W key combination can be used to close the main WinRAR window also as WinRAR viewer windows. "View as Windows text" shortcut in WinRAR viewer changed from Ctrl+W to Ctrl+I.

what's new9. New command line switch -r- disables recursion completely. So 'rar a -r- arc dirname' command will add only the empty dirname folder and ignore its contents. By default, if dirname does not include wildcards, RAR adds its contents even if -r switch is not specified.

what's new10. If used when extracting, the new command line switch -ai forces RAR to ignore file attributes. When using this switch, extracted files will always have attributes assigned by operating system to a newly created file by default.

what's new11. If output file name is not specified in "cw" command, console RAR will send comment data to stdout.

what's new12. When compressing stdin data with -si[name] switch, RAR sets modification time of archived entry to current system time. Previous RAR versions did not fill this field, resulting in meaningless modification time for stdin.

what's new13. Message displayed when you place the mouse cursor on WinRAR tray icon includes the archive name now. Previously only time left and total percent were displayed for archiving operations.

what's new14. New 'Shutdown' variable in 'Software\WinRAR\Policy' registry key allows to disable "Turn PC off when done" option for security reasons. Read "Configuration settings/Registry variables" for more details.

what's new15. Better shell extension performance. Now WinRAR context menu will be more responsive when working with thousands of selected files.

what's new16. Improved compatibility with high DPI Windows display mode.

what's new17. Bugs fixed:

a) WinRAR could fail to open tar or tar.gz archive if such archive contained a file larger than 8 GB;

b) WinRAR context menu did not work properly in Windows 7 beta if icons in context menus were enabled and user clicked a file inside of Windows 7 Library folder;

c) previous WinRAR versions failed to rename files having 5 or more continuous spaces in the name. WinRAR shell does not display such spaces for safety reasons, because they can hide an actual file extension. But this security measure prevented the rename command to work properly.

RAR - What's new in the Version 3.8

Bugs fixed:
a) Corrected a bug in multithreaded text compression module, which under some circumstances might result in corrupt archived data. This bug was present only in multithreaded mode and only in WinRAR 3.60. RAR versions for other platforms are not affected.

b) Resolved a compatibility issue preventing WinRAR 3.60 to run in Windows 95.

RAR - What's new in the Version 3.60

1. Multithreaded version of RAR compression algorithm improves the compression speed on computers with several CPU,
dual core CPU and processors with hyperthreading technology. Multithreading is enabled by default, but you can disable it
in "General" part of "Settings" dialog.
In the command line mode you can control multithreading with -mt switch.

2. WinRAR can display the folder tree panel allowing to navigate in disk and archive folders. Use "Options/Folder tree" submenu to enable the folder tree. It can be configured separately in file and archive management modes.
Folder tree replaces "Browse for folder" command previously available in "File" menu and uses its Ctrl+T keyboard shortcut.

3. Now WinRAR "Rename" command also works with ZIP archives. Previous versions could rename files only in RAR archives.

4. Added decompression of LZH archives created with "-lh7-" algorithm.

5. New "Remove duplicate folders from extraction path" option in "Settings/Compression" dialog.
If this option is on and you unpack an archive which root folder has no files and only one 'somename' folder and if destination
folder is new or empty and also ends with '/somename', WinRAR will exclude one 'somename' from resulting 'somename/somename' path.

6. New "Define volume sizes..." button in "Settings/Compression". This button activates "Define volume sizes" dialog. Here you can customize the list of predefined volume sizes associated with "Split to volumes, bytes" field in archiving dialog.

7. Speed of RAR general compression increased for some data types. Depending on data type and size the gain may achieve 5 - 15%.

8. New "Rename automatically" option in the extraction dialog and command line -or switch to rename extracted files automatically if file with the same name already exists. You can also enable the auto-renaming mode directly from the overwrite confirmation prompt with "Rename All" button.
Renamed files will get names like 'filename(N).txt', where 'filename.txt' is the original file name and 'N' is a number.

9. "Set modification time" option in "Advanced" part of extraction dialog is accessible also for ZIP archives. Previously it could be changed only for RAR archives.

10. "Multithreading" option added to "Benchmark and hardware test" command, so you can compare performance of usual and multithreaded versions of RAR compression algorithm.

11. New 'ch' (change archive parameters) command line mode command. Its purpose is to apply switches like -av, -tl and -cl to archive.

12. New 'cv' command line mode command. It provides the command line interface to WinRAR "Convert archives" command. It is supported only by winrar.exe, not by rar.exe.

13. New command line -sl and -sm switches to set size limits of processing files.

14. New command line -fcu[file] switch allows to read archive comments from Unicode files. It also modifies behavior
of "cw" command, setting the comment output format to Unicode.

15. 7Z added to list of formats stored without compression when using -ms switch without a parameter.

16. Switch -e[+] is now supported by most of command line operations including extracting and deleting files. Previously
it was supported by only archiving command.

17. It is allowed to use environment variables in archive name in archiving dialog, in destination path in extraction dialog,
in folder names on "Compression" and "Paths" pages in WinRAR settings. For example, you can enter '%temp%' in "Folder for
temporary files" field.

RAR - What's new in theVersion 3.5
1. Now it is possible to change WinRAR's look by installing interface themes. Theme files are available on http://www.rarlab.com/themes.htm Theme files are RAR archives, just open them in WinRAR to install. You can manage installed themes using "Options/Themes" menu.
2. WinRAR supports decompression of ZIP archives created using Zip64 format extension. Zip64 was introduced to remove original ZIP format limitations on archived file size.
3. Added support of multivolume (multipart) CAB archives.
4. New options in "Advanced" part of extraction dialog: a) "Delete archive" options allow to delete extracted archives; b) "Check authenticity information" option controls processing of authenticity information in RAR archives.
5. "Wait if other WinRAR copies are active" option in "Advanced" parts of archiving and extraction dialogs. If enabled, it waits while other WinRAR copies are creating, modifying or unpacking an archive and starts the operation only when other WinRAR tasks are complete. If you are going to perform several archiving or decompressing tasks, such queued execution can help to reduce the amount of disk seeks and improve overall performance.
6. WinRAR is able to integrate to Windows context menus also on Windows x64 systems.
7. SFX modules:
a) SFX modules are not compressed by UPX anymore, so they are larger now. UPX compression caused numerous false alerts by antivirus software. If you wish to use compressed modules, you can get UPX from http://upx.sourceforge.net and compress *.sfx files in WinRAR folder;
b) The default SFX logo can be replaced by a custom bitmap file. You can do it either with "Load SFX logo from the file" option in "Text and icon" part of "Advanced SFX options" dialog or using -iimg command line switch. Note that -iimg is not supported by console RAR, only GUI WinRAR recognizes it. This option is not supported in Windows 95, 98 and Me. Also you cannot use it if you compressed SFX modules by UPX.
c) It is possible to specify user defined SFX icons larger than 32x32 and with any color depth. Like the previous item, this improvement is valid only if SFX modules are not compressed by UPX and your operating system is not Windows 9x/Me;
d) DOS.SFX module moved to RAR/DOS32 distributive. If you need to create DOS SFX archives using WinRAR, just copy DOS.SFX to WinRAR folder.
8. "Wizard" command allows to specify a password when creating or updating an archive.
9. Previous WinRAR versions unpacked the complete archive contents if the user pressed Enter or double clicked on *.exe, *.htm and *.html files. Now it is possible to define file masks to unpack everything for. Such masks can be entered on the "Viewer" page of the "Settings" dialog. For example, if you wish to unpack only a file under the cursor when you double click on archived HTML file, remove "*.htm *.html" from this field.
10. Additional file name extensions for archive formats supported by WinRAR can be specified in the "User defined archive extensions" field on the "Integration" page of the "Settings" dialog. For example, if you have files with ".001" extension, which are in RAR format, you can enter "001" here to associate WinRAR with such files.
11. New "Show encrypted or compressed NTFS files in color" option in "File list" page of "Settings" dialog.
12. New "Lock toolbars" option in "General" page of "Settings" dialog and in the menu displayed after clicking the right mouse button on the toolbar. "Lock toolbars" prevents accidental toolbar moving or resizing.
13. "Repair" and "Extract" commands replace invalid characters (colon, question mark, etc.) by underscore also in file names in ZIP archives. Previously WinRAR did it only for RAR archives.
14. New -n and -n@ switches set additional include filters, so only files matching the mask will be processed.
15. New -id[c,d,p,q] switch. Additionally to previously available -idp switch (disable percentage indicator), switches -idc, -idd and -idq instruct the console RAR to hide the copyright message, "Done" message and all information messages.
16. Switch -e+ allows to specify file include attributes mask. For example, you can use -e+h switch to compress only hidden files.
17. Switch -ver[n] supports the optional 'n' parameter also when archiving. It limits the maximum number of file versions.
18. If the short name of an already existing file is equal to the long name of an unpacking file, WinRAR changes the short name of the already existing file before unpacking. In such situation previous versions prompted to overwrite the existing file even though long file names were not equal.
19. Security changes: a) WinRAR shell does not allow to run *.pif files. Archived PIF files is one of typical ways for computer viruses to distribute; b) WinRAR shell does not allow to run files having 5 or more continuous spaces in the name. For example, "calc.txt .exe". Viruses frequently add such spaces to confuse users and hide the real extension. WinRAR shell removes these continuous spaces except first and last also when displaying names of such files in the file list.
20. In Windows XP WinRAR highlights the sorted column in the file list using the different color, like it is done in Windows Explorer.
