bz2
What is a .bz2 file?
application/x-bzip2
BZ2 is a file compressed with bzip2, which uses the Burrows-Wheeler transform to achieve higher compression ratios than gzip at the cost of slower speed. Like gzip, it compresses a single stream rather than archiving multiple files. It is common for distributing large source and data files.
How to use a .bz2 file
Use an example BZ2 to test bzip2 decompression, block-based decoding, and pipelines that select among gzip, bzip2, and xz codecs.
