Notes:

^ Application is only for decompression.
^ GNU tar calls the external programs gzip and bzip2 to perform compression; these external programs usually come with systems that contain GNU tar.
^ Allows adding of a variable amount of redundancy for much better error recovery. See also RAR (file format).
^ BitZipper uses various methods to extract data from damaged files.
^ 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. Currently, only supported by 7z (7-Zip), RAR (WinRAR) and RK (WinRK) archives.
^ 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 "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.

Notes:

^ Used to, but no longer does, due to technical and legal issues. More info
^ GNU tar calls external programs[1] (like compress, gzip or bzip2 or any other programs working with abstract streams and supporting the "-d" option) to perform (un)compression, and allowing you to implement your own filters^[2]. These external programs may be shipped with your Operating System.
^ GNU tar let you to implement your own filters[3], allowing you to use others compression program (p7zip, ...) and others filters (GPG, ...).
^ Starting from version 11.
^ Requires external program. More info
^ ALZip also reads: alz, ace, arc, arj, b64, bh, bhx, bin (hex files), bin (CD images), bz2, cab, ear, enc, gz, ha, ice, iso, jar, lcd, lha, lzh, mim, pak, rar, tar, tgz, uue, uu, war, xxe, z, zip, zoo, 7z, and 001
^ 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.
^ Decompression of ZIP archives can fail with 7-Zip, depending on which archiver was used for the ZIP.
^ XAD is modular and supports virtually up to 300 archive methods and file types. Its GUI (Voodoo-X) supports 80 archive types. So all archives included in the comparison list should be (more or less) managed by XAD.
^ Requires external programs.[4]
^ Requires external program.[5]

^ StuffIt Expander not included in this list because it only expands archives.

Comparison of efficiency

The table below is meant for comparison purposes and are approximate. [9] The percentage figures are the percentage of the size of the uncompressed file: the lower the percentage, the better compression.

Name	Text %	Text time (s)	Executables %	Executables time (s)	Raw images %	Raw images time (s)
7-zip	19	18.8	27	59.6	50	36.4
bzip2	20	4.7	37	32.8	51	20.0
rar	23	30.0	36	275.4	58	52.7
advzip	24	21.1	37	70.6	57	41.6
gzip	25	4.2	39	23.1	60	5.4
zip	25	4.3	39	23.3	60	5.7
lha	27	3.7	40	13.2	61	9.3

Note: RAR version used was an old version that is different from current versions (see source).

Uncommon archive format support

Some archivers support file extraction from .msi and .iso formats as well. These include WinRAR, PowerArchiver, ALZip, IZArc, and 7-zip.

PeaZip has full support for LPAQ and some PAQ formats (PAQ8F/JD/L/O), and for its native PEA format.
