# bzip2 / bzip

`bzip2` is a compression program.

The bzip2 kioslave is not directly usable, and is intended for use as a filter. For example, the tar kioslave can filter a file through the bzip2 kioslave, in order to display the contents of a `tar.bz2` file directly in a &konqueror; window.

If you click on a file compressed with a `.bz2` in &konqueror;, this kioslave is used to uncompress it and display it as a normal (uncompressed) file.

If you are a developer, and would like to use the bzip2 filter, you can find documentation on using kioslaves at http://techbase.kde.org

See the manual: bzip2.

`bzip` is the ancestor of bzip2. It is rarely used today, having been replaced with bzip2, which offers much better compression.
