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.
Compression schemes used in multiple formats
Specific formats/programs
- 7z

- compress (.Z)
- CCITT Group 4
- CrLZH (.?y?)
- CRN (.crn) - compressed text files used for PC-Write manual
- Crunch (.?z?)
- DiskDoubler
