Files with Z8 extension are associated with Infocom and used for Infocom game modules for Z-machine version 8. Z8 files contain Z-machine instructions called story files or Z-code files. Z-code files end in .z1 to .z7 or .z8 with the number as Z-machine version that runs the file.
Z8 files are rarely opened directly. There is little software that can open and work with Z8 files. Z8 files are part of the Z-machine, a game engine by Infocom for text adventure games like Zork. Z-code stores game source code run by a Z-machine interpreter maintained by community members. Z-code uses the Zork Implementation Language. File extensions use numbers for the Z-machine version to run them.
