It typically compresses files to within 10% to 15% of the best available techniques
The bzip2 application was designed to be a 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 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.
- Because (by now, late 2007) everybody else uses it too.
What\"s New in This Release: [ ]
· Security fix only. Fixes CERT-FI 20469 as it applies to bzip2.
Bzip2 1.0.5 is a compression software application. The Bzip2 compression software adds 10% to 15% more extra space to your disk drive, USB thumb drive, CDs, backup tapes, zip drives, etc The application reduces download time and the transfer of files from one device to another. If you are familiar with GNU Gzip you will be able to use Bzip2 with ease because the command lines are similar.
Bzip2 is not the fastest compressor but it functionality is of top quality when compared to other compressor applications. Bzip is an open source program (BSD-style license)
that is patent free. The open source code allows you to modify the program to suit your needs and use the application on different technology devices. Bzip2 operates
on 32 or 64 bit machines with an ANSI compiler. The software can also be used on Unix and Win32 systems.
If there are decompression errors when decompressing files using Bzip2. The application will perform a self-check and notify you of any errors when decompressing files. Bzip will decompress undamaged files. Bzip2 does not guarantee a full recovery of files but
the application will search for files on disk or tape that can be decompressed.
