Unzip
1. Term used to describe the process of exploding a file using a software utility such as PKUNZIP, Winzip, 7-Zip. For example, many of the programs available for download are compressed into one file making it easier to download one smaller file instead of dozens or hundreds of files that program contains. When that file is downloaded, if the downloaded file ends with .zip it must be unzipped before it can be installed.
2. Unzip is also a command line command used in Linux, Unix, and other command lines. See the unzip command for further information.
