ZIP files have a user interface with icons that make it a file system that can be easily navigated. Originally invented in 1989 by Thom Henderson through PKWARE, the PKZIP utility was quickly supported by Microsoft Windows. Later, Apple built in support for ZIP files in their Mac OS X operating system (10.3 and above).
