Gzip Compressed File (.GZ)
GZ (gzip) is a compression format using the DEFLATE algorithm, developed by Jean-loup Gailly and Mark Adler as a free replacement for the Unix compress utility. Gzip compresses a single file or data stream and is most commonly used in combination with TAR to create .tar.gz archives. It is the standard compression format for web content delivery via HTTP compression.
