File type specification:

Various data file type icon Various data file type

The VMF file extension 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.

The .vmf 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.

How to convert:

As far as we know, this .vmf file type can't be converted to any other file format. This is usually the case of system, configuration, temporary, or data files containing data exclusive to only one software and used for its own purposes. Also some proprietary or closed file formats cannot be converted to more common file types in order to protect the intellectual property of the developer, which is for example the case of some DRM-protected multimedia files.
