File type specification:

Font and typeface file type icon Font and typeface file type

mmm file icon: mmm filetype icon

The MMM file extension is associated with a multiple-master font file format. It is a (PostScript Type1) font which contains, in one font description several extreme styles of a font family and code for interpolating between them to produce intermediate designs. Apple has a similar concept for TrueType -- The only name I've seen given to this is "Apple Distortable Font" -- I call both multiple master.

A multiple master font has several axes along which variation may occur. For example a font might allow variation along the Weight axis (everything from Thin to Black), along the Width axis (Condensed to Extended) and along the Optical Size axis (from 6pt to 72pt). The Type1 spec requires that there be a design for every extreme combination along each axis.
