The mmm file extension is associated with the MultiMedia Movie format. It was introduced in 1991 by Microsoft and IBM, and was presented by Microsoft as the default format for Windows 3.1 multimedia files.

It is based on Electronic Arts's Interchange File Format, introduced in 1985, the only difference being that multi-byte integers are in little-endian format, native to the 80x86 processor series used in IBM PCs, rather than the big-endian format native to the 68k processor series used in Amiga and Apple Macintosh computers, where IFF files were heavily used.

The MultiMedia Movie format was also used by MacroMind Director (Adobe Director).

This mmm file type entry was marked as obsolete and no longer supported file format.

This type of file is no longer actively used and is most likely obsolete.
