Etymology

The word "unzip" combines the prefix "un-" (Old English "un-", meaning "not" or "reverse action") with "zip" (a 20th-century onomatopoeic term for the sound of a fast-moving fastener). Originally tied to physical zippers, its usage expanded in computing to describe file decompression, metaphorically "opening" compressed data.
