WinRAR is an archiving utility that completely supports RAR and ZIP archives and is able to unpack CAB, ARJ, LZH, TAR, GZ, ACE, UUE, BZ2, JAR, ISO, 7Z, Z archives. It consistently makes smaller archives than the competition, saving disk space and transmission costs.
WinRAR offers a graphic interactive interface utilizing mouse and menus as well as the command line interface. WinRAR is easier to use than many other archivers with the inclusion of a special "Wizard" mode which allows instant access to the basic archiving functions through a simple question and answer procedure.
WinRAR offers you the benefit of industry strength archive encryption using AES (Advanced Encryption Standard) with a key of 128 bits. It supports files and archives up to 8,589 billion gigabytes in size. It also offers the ability to create selfextracting and multivolume archives. With recovery record and recovery volumes, you can reconstruct even physically damaged archives.
- "Name encoding" submenu in "Options" menu allows to select encoding for archived file names. This selection affects archive browsing and extraction commands. You can use Ctrl+E keyboard shortcut to access this menu quickly. It can be useful when unpacking an archive without Unicode file names.
- If RAR recovery volumes (.rev files) are present in the same folder as usual RAR volumes, archive test command verifies .rev contents after completing testing .rar files. If you wish to test only .rev files without checking .rar volumes, you can select .rev files in WinRAR file list and apply "Test" only to them or run: rar t arcname.part1.rev in the command line.
- While NTFS file system permits file names with trailing spaces and dots, a lot of Windows programs fail to process such names correctly. If "Allow potentially incompatible names" option in "Advanced" page of extraction dialog is turned off, WinRAR removes trailing spaces and dots, if any, from file names when extracting. This option is turned off by default. Command line RAR also removes trailing spaces and dots when extracting unless -oni switch is specified.
- Previously "Synchronize archive contents" update mode(-as command line switch) aborted if some of archiving folders could not be read. Now WinRAR continues performing the operation and preserves archived files matching unreadable folders.
- WinRAR Shift+Del delete command can be used to delete folders containing non-standard file names with trailing spaces and dots. Usual delete to Recycle Bin also as Shift+Del in previous WinRAR versions cannot delete such folders.
- You can drag folders from folder tree panel and drop them to other programs or Desktop to copy or unpack them. Drag the archive icon in tree panel root to unpack the entire archive.
- "New folder" button in extraction dialog proposes a new folder name based on archive name instead of generic "New Folder".
- Command line RAR version information:
* if -iver switch is specified, RAR displays the version number and quits. You can run just "RAR -iver";
* "x86" or "x64" is displayed in Windows RAR version information both for -iver and in the copyright title for other commands.
- If -p switch is used without optional <pwd> parameter, a password can be also set with file redirection or pipe. For example: rar -p myarc.rar myfiles < psw.txt
- Command line RAR treats 'arcname.partN' as 'arcname.partN.rar' if 'arcname.partN' does not exist and 'arcname.part#.rar' exists.
- Improvements in 7z archives support:
* "Solid" status is correctly detected and reported for 7z archives in WinRAR "Info" command;
* dictionary size is displayed for LZMA and LZMA2 7z archives in WinRAR "Info" command;
* unknown packed size for files inside of 7z solid block is denoted as '?' instead of '0' when browsing the archive contents in WinRAR.
- Maximum comment length for RAR archives is increased from 64 to 256 KB. Since SFX script commands are stored in archive comment, it allows a longer main and license text in SFX archives.
- Size of default WinRAR viewer font is scaled up properly in Windows high DPI mode.
- Switch -scul can be used to process big endian UTF-16 list files as well, provided that they have a correct byte order mark. Previously it allowed only little endian file lists.
- Minimum supported Windows version is Windows XP SP3 now. WinRAR will not run in Windows XP without service packs.
- "Settings/File list/Allow all uppercase names" option is removed. This option was intended to simplify transition from MS DOS to Windows and is not needed anymore.
# Bugs fixed:
- WinRAR 5.31 x64 "Compress and email" command did not work with Microsoft Outlook x64;
- if WinRAR 5.31 version for one of right to left languages was installed in Windows with English or other not right to left system language, WinRAR could change Windows Explorer layout to right to left;
- if archive was stored in a folder without "Write" permission and if archive contents was extracted with drag and drop to a writable folder, WinRAR issued an unnecessary privileges elevation prompt.
