Extractor decompresses and unpacks archive files of type ZIP, GZIP, TAR and JAR. It is meant for everybody who likes to extract archive files here and then without the aim of buying a big archiving application. Extractor is not intended to be overloaded with features, only additional archive types will be added, if possible. The application is freeware, so feel free to use itfree of charge (and at your own risk). As a pure Java application, it is platform independent, thus usable on Windows, Unuix, Linux and MacOS. Extractor can be downloaded as JAR archive. HTML documentation is available from within the application (Menu ''Help'') or online at www.calcom.de/eng/doc/xtract/help.htm. The product home page is www.calcom.de/eng/product/xtract.htm. A german version is availableat www.calcom.de/ger/product/xtract.htm. Java VM required.
