The System suitcase is one of two principal files comprising the classic Mac OS from the original release to OS 9.2.2, the other being the Macintosh Finder. The suitcase is located in the System Folder along with the Finder file and contains keyboard layouts, FKEY resources, sounds, and in System 6, bitmap fonts, and Desk Accessories. In versions released up to and including System 6, the Font/DA Mover has to be used to move these into or out of the System suitcase.
