Name	XPK
Ontology	Electronic File Formats Compression XPK
Released	1992?

XPK is a data compression library system for Amiga computers. It provides standard data compression facilities for use by applications. The name is derived from "eXternal PacKer". The core part of the library is named "XpkMaster".

Support for any number of compression schemes can be added to it. A compression scheme could be well known (e.g. gzip), or could be specific to XPK.

XPK has a native file format, encapsulating a stream compressed with one of its compression schemes.

The main authors of XPK are Urban Dominik Müller, Bryan Ford, Christian von Roques, and Dirk Stöcker. There is also a Unix port, by Vesa Halttunen.
