System suitcase
From Wikipedia, the free encyclopedia
The System suitcase was one of two principal files comprising Mac OS from the original release to System 9.2.2, the other being the Macintosh Finder. The suitcase was located in the System Folder along with the Finder file and contained keyboard layouts, FKEY resources, sounds, and in System 6, bitmap fonts and Desk Accessories.
Prior to System 7, the Font/DA Mover had to be used to move these into or out of the System suitcase. From System 7 and on, the Finder could open and modify the contents of the file. Over the course of subsequent releases, many of the user-serviceable items stored in the System suitcase were moved into separate folders.
[edit] Easter eggs
In System 6, the string "Help! Help! We're being held prisoner in a system software factory!" appears in the data fork of the System file; in System 7, it was updated to "Help! Help! We're still being held prisoner in a system software factory!". Later versions of System 7 alter the message further. A list of credits also follows in each case.
