BZ2 — Bzip2 Compressed File

document

BZ2 is a single-file compression format using the bzip2 algorithm (Burrows-Wheeler transform + Huffman coding). It consistently achieves 10-15% better compression ratios than gzip for text and source code, making it preferred for bandwidth-sensitive distributions. Like gzip, it compresses only a single file — directories must be bundled with TAR first.
