Zip archives are commonly found on ms-dos systems.

Zip and unzip are both compatible with archives created by pkware(r)'s pkzip for ms-dos, but the programs' options and default behaviors do differ in some respects.
Install the unzip package if you need to list, test or extract files from a zip archive.
