List of archive formats

This is a list of file formats used by archivers and compressosrs used to create archive files.

Archive formats by purpose

Archive formats are used for backups, mobility, and archiving. Many archive formats compress the data to consume less storage space and result in faster transfer times as the same data is represented by fewer bytes. Another benefit is that files are combined into one archive file which has less overhead for managing or transferring. Many compression algorithms are available to losslessly compress archived data; some algorithms are designed to work better (smaller archive or faster compression) with some data types. Archive formats are used by Unix-like and Windows operating systems to package software for easier distributing and installing than binary executables.

Archiving only

File extension(s)1MIME type2Official name3Platform4Description
.a, .arapplication/x-archiveUnix ArchiverUnix-likeThe traditional archive format on Unix-like systems, now used mainly for the creation of static libraries.
.cpioapplication/x-cpiocpioUnix-likeRPM files consist of metadata concatenated with (usually) a cpio archive. Newer RPM systems also support other archives, as cpio is becoming obsolete. cpio is also used with initramfs.
.sharapplication/x-sharShell archiveUnix-likeA self-extracting archive that uses the Bourne shell (sh).
.LBR.LBRCP/M

DOS

A system for storing multiple files. LBR archives typically contained files processed by SQ, or the archive itself was compressed with SQ. LBR archives that were compressed with SQ ended with the extension .LQR
.isoapplication/x-iso9660-imageISO-9660 image(Various; cross platform)An archive format originally used mainly for archiving and distribution of the exact, nearly-exact, or custom-modified contents of an optical storage medium such as a CD-ROM or DVD-ROM. However, it can be used to archive the contents of other storage media, selected partitions, folders, and/or files. The resulting archive is typically optimized for convenient rendering to (re-)writable CD or DVD media.
.lbrCommodore 64/128A library format used primarily on the Commodore 64 and 128 lines of computers. This bears no resemblance to the DOS LBR format. While library files were quick to implement (a number of programs exist to work with them) they are crippled in that they cannot grow with use: once a file has been created it cannot be amended (files added, changed or deleted) without recreating the entire file.
.marMozilla ARchive5(Various; cross platform)An archive format used by Mozilla for storing binary diffs. Used in conjunction with bzip2.
.sbxapplication/x-sbxSeqBox6(Various; cross platform)A single file container/archive that can be reconstructed even after total loss of file system structures.
.tarapplication/x-tarTape archiveUnix-likeA common archive format used on Unix-like systems. Generally used in conjunction with compressors such as gzip, bzip2, compress or xz to create .tar.gz, .tar.bz2, .tar.Z or tar.xz files.

Compression only

File extension(s)7MIME type8Official name9Platform10Description
.brapplication/x-brotliBrotliallBrotli is a compression algorithm developed by Google for textual web content, and typically achieves higher compression ratios than other algorithms for this use case.
.bz2application/x-bzip2bzip2Unix-likeAn open source, patent- and royalty-free compression format. The compression algorithm is a Burrows–Wheeler transform followed by a move-to-front transform and finally Huffman coding.
.F, .?XF11Freeze/melt12QNX4, Unix-like and DOSOld compressor for QNX4 OS. The compression algorithm is a modified LZSS, with an adaptive Huffman coding.
.genozipapplication/vnd.genozipgenozipLinux, macOS, WindowsGenozip, a compressor for genomic file formats such as FASTQ, BAM, VCF and others.13
.gzapplication/gzip14gzipUnix-likeGNU Zip, the primary compression format used by Unix-like systems. The compression algorithm is Deflate, which combines LZSS with Huffman coding.
.lzapplication/x-lziplzipUnix-likeAn alternate LZMA algorithm implementation, with support for checksums and ident bytes.
.lz4LZ4Unix-likeAlgorithm developed by Yann Collet, designed for very high (de)compression speeds. It is an LZ77 derivative, without entropy encoding.
.lzmaapplication/x-lzmalzmaUnix-likeThe LZMA compression algorithm as used by 7-Zip.
.lzoapplication/x-lzoplzopUnix-likeAn implementation of the LZO data compression algorithm.
.rzrzipUnix-likeA compression program designed to do particularly well on very large files containing long distance redundancy.
.sfarksfArkWindows compress/decompress- Linux and macOS decompress onlyA compression program designed to do high compression on SF2 files (SoundFont).
.szapplication/x-snappy-framedSnappyUnix-likeA compression format developed by Google, and open-sourced in 2011. Snappy aims for very high speeds, reasonable compression, and maximum stability rather than maximum compression or compatibility with any other compression library. It is an LZ77 derivative, without entropy encoding.
.?Q?SQCP/M and DOSSqueeze: A program which compressed files using Huffman coding. A file which was "squeezed" had the middle initial of the name changed to "Q", so that a squeezed text file would end with .TQT, a squeezed executable would end with .CQM or .EQE. Typically used with .LBR archives, either by storing the squeezed files in the archive, or by storing the files decompressed and then compressing the archive, which would have a name ending in ".LQR".
.?Z?CRUNCHCP/M and DOSA compression program written by Steven Greenberg implementing the LZW algorithm. For several years in the CP/M world when no implementation was available of ARC, CRUNCHed files stored in .LBR archives were very popular. CRUNCH's implementation of LZW had a somewhat unusual feature of modifying and occasionally clearing the code table in memory when it became full, resulting in a few percent better compression on many files.
.xzapplication/x-xzxzUnix-likeA compression format using LZMA2 to yield high compression ratios. The LZMA algorithm is an LZ77 derivative, with entropy encoding in the form of range encoding.
.zapplication/x-compresspackUnix-likeThe traditional Huffman coding compression format.
.Zapplication/x-compresscompressUnix-likeThe traditional LZW compression format.
.zstapplication/zstdZstandardCross-platformAlgorithm developed by Yann Collet at Facebook, combining high speed and high compression. It is an LZ77 derivative, with entropy encoding in the form of finite-state entropy and Huffman coding.
.??_MS-DOS/WindowsCompression format(s) used by some DOS and Windows install programs. MS-DOS includes expand.exe to decompress its install files. The compressed files are created with a matching compress.exe command. The compression algorithm is LZSS.

.sdaSelf Dissolving ARChiveCommodore 64, Commodore 128Commodore 64, Commodore 128YesSDAs refer to Self Dissolving ARC files, and are based on the Commodore 64 and Commodore 128 versions of ARC, originally written by Chris Smeets. While the files share the same extension, they are not compatible between platforms. That is, an SDA created on a Commodore 64 but run on a Commodore 128 in Commodore 128 mode will crash the machine, and vice versa. The intended successor to SDA is SFX.
.seaSelf Extracting ArchiveClassic Mac OSClassic Mac OS (implicitly)A pre-Mac OS X Self-Extracting Archive format. StuffIt, Compact Pro, Disk Doubler and others could create .sea files, though the StuffIt versions were the most common.
.senSciferMultipleMultipleYesScifer Archive with internal header
.sfxSelf Extracting ArchiveCommodore 64, Commodore 128Commodore 64, Commodore 128YesSFX is a Self Extracting Archive which uses the LHArc compression algorithm.

  33. File extensions may differ across platforms. The case of these extensions may differ on case-insensitive platforms.

  34. MIME media types may be conjectural. Very few have been officially registered with the IANA. Compression-only formats should often be denoted by the media type of the decompressed data, with a content coding indicating the compression format. /wiki/MIME

  35. Official names may be disputed.

  36. Creation platform indicates the platform(s) under which a format can be created.

  39. The DOS and Windows operating systems required filenames to include an extension (of at least one, and typically 3 characters) to identify the file type. Such extensions must be unique for each type of file. Many operating systems identify a file's type from its contents without the need for an extension in its name. However, the use of three-character extensions has been embraced as a useful and efficient shorthand for identifying file types.

  40. Archive files are often stored on magnetic or other media subject to storage errors. Many archive formats contain extra error detection or correction information which can be used by the software used to read the archive files to detect and possibly correct errors.

  41. Many archive formats contain redundant data embedded in the files in order to detect data storage or transmission errors, and the software used to read the archive files contains logic to detect and correct errors.

  42. Many archive formats include the capability to encrypt contents to prevent unauthorised access, using one of many available encryption methods.

  43. While the original tar format uses the ASCII character encoding, current implementations use the UTF-8 (Unicode) encoding, which is backwards compatible with ASCII. /wiki/Tar_(file_format)

  48. The PAQ family (with its lighter weight derivative LPAQ) went through many revisions, each revision suggested its own extension. For example: ".paq9a".

  49. From 3.20 release RAR can store modification, creation and last access time with the precision up to 0.0000001 second (0.1 μs).[24][25]

  51. WIM can store the ciphertext of encrypted files on an NTFS volume, but such files can only by decrypted if an administrator extracts the file to an NTFS volume, and the decryption key is available (typically from the file's original owner on the same Windows installation). Microsoft has also distributed some download versions of the Windows operating system as encrypted WIM files, but via an external encryption process and not a feature of WIM. /wiki/Ciphertext
