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
- 9CDR (Amiga FileImploder Clone)
- BARF (.x, .x??)
- bzip2 (.bz2)
- CCITT Group 4
- CrLZH (.?y?)
- CRN (.crn) - compressed text files used for PC-Write manual
- Crunch (.?z?)
- DiskDoubler
- DUPA (Amiga FileImploder Clone)
- Error Code Modeler (.ecm)
- File Imploder (Amiga) (.imp)
- Freeze/Melt (Unix) (.F)
- gzip (.gz)
- JCalG1 (.jc, Commodore Amiga)
- LZIP (.lz)
- LZMA (.lzma)
- LZOP (.lzop)
- pack (.z)
- Softdisk Text Compressor (.ctx)
- Squash - single file compression on RISC OS
- Squeeze/SQ (.?q?)
- XZ (.xz)
