- bzip2 is a freely available, patent free, high-quality data compressor.
- It typically compresses files to within 10%% to 15%% of the best available
- techniques, whilst being around twice as fast at compression and six times
- faster at decompression.
-
- bzip2 compresses files using the Burrows-Wheeler block-sorting text
- compression algorithm, and Huffman coding. Compression is generally
- considerably better than that achieved by more conventional LZ77/LZ78-based
- compressors, and approaches the performance of the PPM family of statistical
- compressors.
-
- The archive file format of bzip2 (.bz2) is incompatible with that of its
- predecessor, bzip (.bz)."
