Bzip2

Common card · No. 356456

bzip2 is a file format and a file compression program. The program uses the Burrows–Wheeler algorithm to compress and decompress a single file using the bzip2 file format. libbzip2 is a lossless data compression software library used by the bzip2 program. bzip2 is not a file archiver and thus relies on separate external utilities such as tar for tasks such as handling multiple files, and other tools for encryption, and archive splitting. bzip2 was initially released in 1996 (originally named bzip) by Julian Seward. It compresses most files more effectively than older LZW and Deflate compression algorithms but is slower. bzip2 is particularly efficient for text data, and decompression is relatively fast. The algorithm uses several layers of compression techniques, such as run-length encoding (RLE), Burrows–Wheeler transform (BWT), move-to-front transform (MTF), and Huffman coding. bzip2 compresses data in blocks between 100 and 900 kB and uses the Burrows–Wheeler transform to convert frequently...
