Z-machine Z-code File

Developer by: Infocom Category: Game Files

File used by Z-machine, a discontinued game engine used for running text adventure games; stores source code for the game; commonly run by a Z-machine interpreter, several of which have been maintained by community members.

Z-code files use a programming language called the Zork Implementation Language (Zork was Infocom's first game). The file extensions use a numerical value for the version of the Z-machine that is used to run them. Examples include the .Z2, .Z3, .Z4, .Z5, .Z6, .Z7, and .Z8 extensions. Since version 8 was the last Z-machine version, Z8 is the most popular of the extensions.

NOTE: Z1 files are extremely rare, since very few games were released with the Z1 extension.
