Concept
The following tables compare general and technical information for a number of s. 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. Note: Archivers with names cell background highlighted in purple are no longer in development. Basic general information about the archivers. Notes: 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: Information about what common archiver features are implemented natively (without third-party add-ons). Notes: Information about what archive formats the archivers can read. External links lead to information about support in future versions of the archiver or extensions that provide such functionality. Note that gzip, bzip2 and xz are compression formats rather than archive formats. Notes: Information about what archive formats the archivers can write and create. External links lead to information about support in future versions of the archiver or extensions that provide such functionality. Note that gzip, bzip2 and xz are compression formats rather than archive formats. Notes: Tar implementations call the external programs gzip and bzip2, 7z, xz, ... to perform compression; these external programs usually come with systems that contain tar. Requires rar.exe from WinRAR. Requires external program(if you are using WinZip 11.1 or earlier). Requires Ace32.exe from WinAce. The Extractor and XAD are not included in this list because they only expand archives. ALZip can also write to the following formats: BH, JAR, and LZH Updating archives is not supported.
