What is a Z7 file?
Z-code game file used by the Z-machine game engine , which was used for playing text adventure games in the late 1970s and 80s; contains source code for the game; includes graphics referenced in the game; commonly run by a Z-machine interpreter, examples of interpreters are listed in the programs section; similar to the .ULX file.
The Z7 file uses a programming language called the Zork Implementation Language (Zork was Infocom's first game). All of the Z-code file extensions use a numerical value for the different Z-machine versions that are used to run them. Examples include the .Z1, .Z2, .Z3, .Z4, .Z5, .Z6, and .Z8 extensions.
NOTE: Along with Z4 and Z6 files, Z7 file extensions are rarely used.
