bzip2 manufacturer description

bzip2 1.0.6 is a freely available, patent free (see below), high-quality data compressor. It typically compresses files to within 10% to 15% of the best available techniques (the PPM family of statistical compressors), whilst being around twice as fast at compression and six times faster at decompression.

Why would I want to use it?

  • Because it compresses well. So it packs more stuff into your overfull disk drives, distribution CDs, backup tapes, USB sticks, etc. And/or it reduces your customer download times, long distance network traffic, etc. It`s not the world`s fastest compressor, but it`s still fast enough to be very useful.

  • Because it`s open-source (BSD-style license), and, as far as I know, patent-free. (To the best of my knowledge. I can`t afford to do a full patent search, so I can`t guarantee this. Caveat emptor). So you can use it for whatever you like. Naturally, the source code is part of the distribution.

  • Because it supports (limited) recovery from media errors. If you are trying to restore compressed data from a backup tape or disk, and that data contains some errors, bzip2 File compression may still be able to decompress those parts of the file which are undamaged.

  • Because you already know how to use it. bzip2`s command line flags are similar to those of GNU Gzip, so if you know how to use gzip, you know how to use bzip2.

  • Because it`s very portable. It should run on any 32 or 64-bit machine with an ANSI C compiler. The distribution should compile unmodified on Unix and Win32 systems. Earlier versions have been ported with little difficulty to a large number of weird and wonderful systems.
