Gzip creates compressed files similar to a Zip or RAR compression utility. The resulting files have a "gz" extension. Gzip and Gunzip provide decompression for any "gz" files on your system. The Gzip compression algorithm is a documented and open source method. This means that other applications are free to include it or create routines to decompress "gz" files. Before installing Gzip or another utility, you may want to check your preferred compression utility for compatibility with "gz" files.
Open your preferred Web browser and navigate to Gzip.org. Download an executable compatible with your operating system. Use it to decompress your "gz" file. Linux includes Gzip installed by default.
