Clzip is a lossless data compressor based on the LZMA algorithm, with very safe integrity checking and a user interface similar to that of gzip or bzip2. Clzip decompresses almost as fast as gzip and compresses better than bzip2, which makes it well suited for software distribution and data archiving. Clzip uses the lzip file format; the files produced by clzip are fully compatible with lzip-1.4 or newer, and can be rescued with lziprecover. Clzip is, in fact, a C language implementation of lzip, intended for embedded devices or systems lacking a C++ compiler.

Release Notes: The "-F, --recompress" option, which forces recompression of a file whose name already has the ".lz" or ".tlz" suffix, has been added. Only one status line is printed for each multimember file when only one "-v" is specified. For large values of "--match-length", compression ratio has been slightly increased and compression time has been reduced by up to 6%.
