What is a MM file?
The .mm file extension is most commonly associated with the FreeMind open source mind-mapping software application. The MM files contain visual diagrams that are created with the software. They are commonly used for research, brainstorming, project management and note taking.
The .mm file extension is also used for Meme virtual reality world files, Metamath ASCII database files, MultiMate Advantage II text document files, Groff source in mm format files, Lightscape material map files, Macro Mania macro files, Rise of Nations campaign media files and Apple Xcode core C program files.
