An archive is a compressed file which is used by WarpIN to install software.

A WarpIN Archive usually has a file extension of .WPI and contains at least one package, plus an installation script which tells WarpIN what should be displayed to the user, what packages are contained in the archive, and what system configuration should be performed.

Note that WarpIN archives can also be self-executing. In that case, the archive has a file extention of .EXE and will call WarpIN by itself, if WarpIN is already installed.
