Opening MMF files

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

What is a MMF file?

MMF is an acronym for Mobile Music File. Files that contain the .mmf file extension store Yamaha SMAF sound format files.

The MMF file format was created for mobile devices. The MMF files most often contain cell phone ring tones, but they can also other objects, such as graphics and text, as well as audio data.

MMF files can be created from WAV and MID files by using the Yamaha SMAF tools.

The .mmf file extension is also used by the Windows NT mail client. These MMF files contain collections of email messages that can be exported into the PST file format using the Microsoft Exchange software application.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
