File type specification:

Game file type icon Game file type

The Z1 file extension is associated with Infocom.

The .z1 files are compiled game code to files containing Z-machine instructions (called story files, or Z-code files). Z-code files usually have names ending in .z1, .z2, .z3, .z4, .z5, .z6, .z7 or .z8 (and occasionally .dat), where the number is the version number of the Z-machine on which the file is intended to be run.

Types 1, 2, 4, 6, and 7 are extremely uncommon; most Z-machine data files are types 3, 5, or 8. Type 6 provides some graphics support.

Interpreters for Z-code files are available on a wide variety of platforms - on various old machines (such as the Apple II, TRS-80 and Sinclair), portable machines (such as Palm OS devices and the Nintendo Game Boy) and most modern platforms.
