lossless data compressor based on LZMA algorithm
Lzip is a lossless data compressor based on the LZMA (Lempel-Ziv-Markov chain-Algorithm) algorithm designed by Igor Pavlov. The high compression of LZMA comes from combining two basic, well-proven compression ideas: sliding dictionaries (i.e. LZ77/78), and markov models (i.e. the thing used by every compression algorithm that uses a range encoder or similar order-0 entropy coder as its last stage) with segregation of contexts according to what the bits are used for. Lzip is not a replacement for gzip or bzip2, but a complement; which one is best to use depends on user's needs.
Related subprojects include:
- Clzip
- A C implementation of lzip for systems lacking a C++ compiler.
- Plzip
- A multi-threaded compressor using the lzip file format.
- Lzlib
- A compression library for the lzip file format.
- Lunzip
- A small decompressor for lzip files.
- Lziprecover
- A data recovery tool and decompressor for lzip files.
- Pdlzip
- A limited, "public domain" implementation of the lzip data compressor,
intended for those who can't distribute GPL licensed Free Software. Pdlzip is also able to decompress legacy lzma-alone (.lzma) files.
