uncompressing (or decompressing)

Part of the Computing fundamentals glossary:

Uncompressing (or decompressing) is the act of expanding a compression file back into its original form. Software that you download from the Internet often comes in a compressed package that can uncompress itself when you click on it. You can also uncompress files using popular tools such as PKZIP in the DOS operating system, WinZip in Windows, and MacZip in Macintosh.
