System suitcase

The System suitcase (so-called because its icon depicts a suitcase; officially called the System file) is one of two essential files that make up the classic Mac OS, the other being the Macintosh Finder.[1][2] If either file is missing or corrupted, a Macintosh may display a blinking question mark when booting.[3] The suitcase is located in the System Folder, like the Finder file,[1] and contains keyboard layouts, FKEY resources, cursors, icons, sounds, and, in System 6, bitmap fonts, and desk accessories.[4][5][6] Mac OS only supports one System file; the presence of more than one System file on a hard disk is likely to cause system instability.[7]
