Compression + archiving
(Multiple files => 1 file, makes it smaller)
- 7z - 7ZIP
 - ACE ace
 - ARC arc
 - arc - ARC (FreeArc)
 - arc, gz - ARC (Web Archiving)
 - dmg - Apple Disk Image
 - arj ARJ
 - BRU - (RSX-11M backup)
 - cab - Cabinet
 - DWC dwc
 - IMP imp
 - Jar j, jar => this is just a renamed zip file with some mandatory files
 - lzh, lha - LHAv
 - PMA (.pma)
 - RAR (.rar)
 - Softlib (Softdisk Publishing)
 - spk - Spark
 - sit - Stuffit
 - sitx - Stuffit X

Archiving only
(many files => 1 file, no compression attempted)
- arc - ARC (Internet Archive)
 - hqx - BinHex
 - LBR lbr
 - tar - Tape Archive
 - a lib - AR file format -- Unix Archiver (ar) format as used by various compilers/linkers
 - CPIO cpio
 - BagIt
 
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.
