Comparison of file archivers

Archivers

General information

Operating system support

1. A separate 64-bit Windows x64 Edition version is also available.
2. The Unix-like system port is known as p7zip. p7zip also is provided by FreeDOS.
3. A Windows Mobile release is available.
4. The programs for other platforms are called Unace, do not have the same GUI, and can only perform decompression.
5. WinRAR is for Windows, RAR for other platforms.
6. This program also has a POSIX version available.
7. General Windows CE version.
8. Also Acorn RISC OS, Atari, MVS, OS/2, VM/CMS, VMS and others.
9. Bundled with Windows 10 since insider build 17063

   Archiver features

1. Application is only for decompression.
2. 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.
3. Allows adding a variable amount of redundancy for much better error recovery. See also RAR.
4. 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.
5. 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.
6. Does support Unicode names, but not under the default option settings: the user must tick "Use OEM conversion for filenames" under "General" on the "Miscellaneous" tab in the Configuration dialog to enable Unicode name support. Full support for Unicode files names by default is supported only for 7-Zip and RAR archive formats.
7. Commandline batch compression is available only for ZIP and ALZ formats.
8. UTF-8 file/path-names support was completed in release 3.0.1 on Unix systems, and in release 5.8.0 on Windows systems. GUI UTF-8 support for full internationalization of the application was completed in release 2.2.0. Optionally, extended characters can be set to be replaced by jolly "?" character for exporting scripts to legacy systems; scripts creation screen informs if commands are ANSI-safe, OEM-codepage-safe, or requires UTF-8 compliant environment to run.
9. Commandline batch compression and expansion requires free add-on software downloaded from the WinZip website.
10. Peazip supports file encryption and file name encryption, although only in certain types of archives, including its own Pea format, 7-zip, zip and Arc.
11. Many shells have built-in zip file support. Windows Explorer has "Send To"->"ZIP-compressed folder".
12. Unicode and volumes since version 3.0. AES since 3.1.

    Archive format support

Reading

1. Used to, but no longer does, due to technical and legal issues.
2. Tar implementations call external programs to perform compression, and allowing you to implement your own filters. These external programs may be shipped with your Operating System.
3. GNU tar lets you implement your own filters , allowing you to use other compression programs and filters.
4. Starting from version 11.
5. Requires external program.
6. Archive Utility itself is unable to open ISO files, but Disk Utility, which also comes with Mac OS X, is able to mount them as virtual disks.
7. Requires external program.
8. Only partial support for reading proprietary SITX format.
9. FreeARC uses .arc as its filename extension, but this format is not the same as the traditional ARC file.
10. Supports these formats as compression stream of other archive formats like tar.bz2 or iso.xz but does not support the format as an archive itself, as they are not archive formats. See the above explanation for tar.
11. B1 Free Archiver for Android and B1 Online Archiver support ARJ format.

    Writing

1. Tar implementations call the external programs gzip and bzip2, 7z, xz,... to perform compression; these external programs usually come with systems that contain tar.
2. Requires rar.exe from WinRAR.
3. Requires external program.
4. Requires Ace32.exe from WinAce.
5. The Extractor and XAD are not included in this list because they only expand archives.
6. ALZip can also write to the following formats: BH, JAR, and LZH
7. Updating archives is not supported.
8. Requires external program.
9. Stuffit supported file formats
10. Ark is a front-end only and requires appropriate command-line programs be installed. Programs like bzip2, gzip, tar, zip usually come with systems that contain Ark; writing in.rar format requires a commercial program.
11. Xarchiver is a front-end only and requires appropriate command-line programs be installed. Programs like bzip2, gzip, tar, zip usually come with systems that contain Xarchiver; writing in.rar format requires a commercial program.
12. Archive Manager is a front-end only and requires appropriate command-line programs be installed. Programs like bzip2, gzip, tar, zip usually come with systems that contain Archive Manager. writing in.rar format requires a commercial program.
13. If there are more than one, files must be grouped in a.tar before being compressed.
14. supports the formats as stream compression of other archive format and can create compressed format like tar.bz2 or iso.xz but cannot create an archive in these formats
15. it is possible to open war and jar files to extract e add/replace file; files war and jar are still valid after that
16. it require console rar.exe, and the path to it -- specified in Options. it can be taken from WinRAR software. PowerArchiever also doesn't support separate definition of the Dictionary Size and Compression Method.

    Uncommon archive format support
