Version history WinRAR (64-bit)

<<Back

Changes from v3.90 -> v3.91 Beta 1

• This version can decompress 7-Zip archives created with LZMA2 algorithm.
• Now a password is requested only once when unpacking 7z archives with encrypted file names from context menu. WinRAR 3.90 asked it twice.
• 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.
• WinRAR displays CRC32 of files inside of usual .gz (not .tar.gz) archives. Previous versions left this field blank for GZIP files.
• Bugs fixed:
• 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);
• WinRAR could display incorrect file names when browsing malformed ZIP archives;
• WinRAR 3.90 failed to decompress LZH archives created with "-lh7-" algorithm;
• 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;
• 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;
• 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.

Changes from v3.80 -> v3.90

• 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.
• 3. "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.
• 4. 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.
• 5. 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.
• 6. "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.
• 7. 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.
• 8. 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.
• 9. 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.
• 10. 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.
• 11. If output file name is not specified in "cw" command, console RAR will send comment data to stdout.
• 12. 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.
• 13. 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.
• 14. 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.
• 15. Better shell extension performance. Now WinRAR context menu will be more responsive when working with thousands of selected files.
• 16. Improved compatibility with high DPI Windows display mode.
• 17. 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.

Changes from v3.90 Beta 4 -> v3.90 Beta 5

• Bugs fixed:
• "Convert" command could fail if original and resulting archives were multivolume and name of original archive included DBCS (Chinese, Japanese or Korean) characters;
• WinRAR did not add "Extract to folder\" item to Windows context menus for ZIP archives if Windows Compressed Folders was active.

Changes from v3.90 Beta 1 -> v3.90 Beta 2

• Delay between right clicking selected files in Windows Explorer and displaying the context menu is reduced. This delay can be noticeable, when you right click several thousands of files.
• Bugs fixed:
• dragging a file over an existing archive in Windows Explorer did not work for 64 bit WinRAR;
• 64 bit beta 1 shell extension crashed if user right clicked "Startup" folder in Start Menu and selected "Open" or "Explore" commands;
• "Scan archive for viruses" command in 64 bit beta 1 could fail to autodetect some of 32 bit antiviruses detected by 32 bit version;
• beta 1 hung when the entire folder specified as a mask was excluded: 'rar a -xfolder arc folder';
• sometimes beta 1 could hang when creating a new RAR archive if archive comment or one of advanced NTFS options was specified;
• ZIP encryption code was updated to include recent InfoZip fixes;
• 64 bit version did not store the toolbar layout.
