Opening MMS files

Did your computer fail to open a MMS file? We explain what MMS files are and recommend software that we know can open or convert your MMS files.

What is a MMS file?

The MMS file format was created by RAD Game Tools, Inc. as a proprietary data file type that uses the .mms file extension. These MMS files are used by their line of audio authoring software products.Also known as Sound Tools files, these .mms files are found in Windows PCs where the Miles Sound System has been installed. This software was also created by RAD Game Tools. The Miles Sound System provides a set of tools that can allow users to create and edit music backgrounds, audio clips and sound effects for their computer game development projects.These .mms files do not contain human-readable data. Only the Miles Sound System software can use these MMS files. It's best to leave these .mms files alone, in order for the audio tools in the Miles Sound System program to continue working properly.
