Compression + archiving
(Multiple files => 1 file, makes it smaller)
- 7ZIP (.7z)
- ACE (.ace)
- ARC (.arc)
- ARC (FreeArc) (.arc)
- ARC (Web archiving) (.arc.gz) See ARC (Internet Archive)
- Apple Disk Image
- ARJ
- BRU - (RSX-11M backup)
- Cabinet (.cab)
- DWC (.dwc)
- IMP (.imp)
- Jar (.j, .jar) => this is just a renamed zip file with some mandatory files
- LHAv (.lzh, .lha)
- PMA (.pma)
- RAR (.rar)
- Softlib (Softdisk Publishing)
- Spark (.spk)
- Stuffit (.sit)
- Stuffit X (.sitx)
- WARC (.warc, .warc.gz)
- ZIP (.zip)
- ZOO (.zoo)
Archiving only
(many files => 1 file, no compression attempted)
- AR file format (.a, .lib) -- Unix Archiver (ar) format as used by various compilers/linkers
- ARC (Internet Archive) (.arc)
- BagIt
- BinHex (.hqx)
- CPIO (.cpio)
- LBR (.lbr)
- Tape Archive (.tar)
Stream compression formats
A stream format takes a stream of bytes, and outputs a different, hopefully smaller, stream of bytes. These compression formats are often used internally in other data structures to compress data, as well as in network protocols, such as http. Used stand-alone, a stream compression format does not offer archiving capability, however in the UNIX doctrine, an archiver like tar can be combined with an archive format to produce a proper compressed archive.
- BZIP2 (.bz2)
- CCITT Group 4
- CrLZH (.?y?)
- Crunch (.?z?)
- GZIP (.gz)
- Error Code Modeler (.ecm)
- LZIP (.lz)
- LZMA (.lzma)
- LZOP (.lzop)
- LZW (.z)
- Squash - single file compression on RISC OS
- Squeeze/SQ (.?q?)
- XZ (.xz)
