ZIP is a very popular data compression format that comes in various different "dialects" and is being used in many applications.

The ZIP file format was originally created by Phil Katz, founder of PKWARE. Katz publicly released technical documentation on the ZIP file format, along with the first version of his PKZIP archiver, in January 1989.

gzip (GNU zip) is a compression utility designed to be a replacement for compress. Its main advantages over compress are much better compression and freedom from patented algorithms. It has been adopted by the GNU project and is now relatively popular on the Internet. gzip was written by Jean-loup Gailly (, and Mark Adler for the decompression code.

gzip produces files with a .gz extension. gunzip can decompress files created by gzip, compress or pack. The detection of the input format is automatic.

The format of the .gz files generated by gzip is described in RFCs (Request For Comments) 1951 and 1952.

Google Bundles Software with WinZip By Nate Mook, BetaNews June 14, 2005, 3:54 PM

In a marketing tactic used primarily by spyware and adware companies, Google has begun bundling its Google Toolbar and Desktop Search software with the popular WinZip archive utility. The move comes as Google begins to expand its bundling effort with a number of leading software applications.

WinZip quietly updated its download executable last week, which now weighs in at close to 4MB with the added Google tools. Users are given the opportunity to opt out of installing the Google software on the first WinZip setup screen; by default the tools are installed.
