'''DMF''' (Distribution Media Format), is a special way of formatting a PC-compatible [[floppy disk]], so that it can store more than the usual amount of data. It was designed (presumably) by Microsoft, and used on some of their distribution disks.

The main DMF format puts 1680KB on what would normally be a [[PC-DOS 1.44M format|1.44M 3.5" floppy disk]]. There is also an 82-track version that has a slightly higher capacity, at the expense of compatibility.

Simply reading a raw DMF [[Disk Image Formats|disk image file]] isn't necessarily problematic. Such a file should be readable by most software that supports images of [[FAT]] filesystems, or [[IMA]] format.
