VMF

It has been suggested that this article or section be merged with VMF documentation. (Discuss)

Valve Map Format/Valve Map File (abbreviated VMF) is a proprietary format that stores raw (pre-compile) map data, used by the Valve Hammer Editor to save production-stage maps and prefabs. It contains information on all map brushes and entities in a script format stored with a ".vmf" extension.

VMF files are written in the same keyvalue text format that the engine uses to parse external configuration files, thus allowing them to be opened and edited in plain text.
