VMF file extension - Valve Map Format
What is vmf file? How to open vmf files?
File type specification:
File extension vmf is associated with the Valve Hammer Editor (WorldCraft) that saves a level file in the .vmf format by default. Before this, it saved a level file in the binary, proprietary .rmf or text-based, human-readable .map format.
VMF format (Valve Map Format) is a simple file that contains all the information about a level in a format vaguely similar to an XML file. It originated because of Half-Life's reliance on the Quake engine, and has remained as a result. Valve includes compiling tools with the Source SDK - vbsp, vvis, and vrad.
