The following tables compare general and technical information for a number of file archivers. Please see the individual products' articles for further information. They are neither all-inclusive nor are some entries necessarily up to date. Unless otherwise specified in the footnotes section, comparisons are based on the stable versions—without add-ons, extensions or external programs. Archivers Note: Archivers with names cell background highlighted in purple are no longer in development. General information Basic general information about the archivers. Notes: Operating system support The operating systems the archivers can run on without emulation or compatibility layer. Ubuntu's own GUI Archive manager, for example, can open and create many archive formats (including Rar archives) even to the extent of splitting into parts and encryption and ability to be read by the native program. This is presumably a "compatibility layer." Notes: A separate 64-bit Windows x64 Edition version is also available. The Unix-like system port is known as p7zip. p7zip also is provided by FreeDOS. A Windows Mobile release (version 9.05-alpha onward) is available. The programs for other platforms are called Unace, do not have the same GUI, and can only perform decompression. WinRAR is for Windows, RAR for other platforms. This program also has a POSIX version available. General Windows CE version. Also Acorn RISC OS, Atari, MVS, OS/2, VM/CMS, VMS and others. Bundled with Windows 10 since insider build 17063 Archiver features Information about what common archiver features are implemented natively (without third-party add-ons). Notes: Application is only for decompression. Traditionally, tar, cpio, or pax calls the external programs gzip and bzip2 to perform compression; these external programs usually come with systems that contain the archiver. This is the case for GNU tar. BSD tar uses its own implementation, since it also has to deal with archive formats that do their own compression. Allows for a variable amount of error correction. See also RAR (file format). Extracting/adding file and/or directory names into archive in either UTF-7, UTF-8 or UTF-16/UCS-2 encoding to support single file/directory name which contains characters from different languages. More recent versions of the zip file format have support for Unicode filenames. In WinRAR 3.60, when opening 7-Zip archives which contains Unicode file/directory names, they will not be displayed correctly. There will be no problem extracting them, however. Does support Unicode names, but not under the default (initial) option settings: the user must tick "Use OEM conversion for filenames" under
