Unfortunately, DRVSPACE files are not plain FAT (or VFAT) images, but
they are compressed with a proprietary algorithm. Hence no support for
it in mtools.

However, there seems to be an *experimental* support for 2.3.x and 2.4
on Dmsdos' website: http://cmp.felk.cvut.cz/~pisa/dmsdos/

If I'll find time (not anytime soon, probably...) I might use their
source code to figure out the algo and integrate it into mtools. This
looks like a major undertaking and would be 3.9.10 or 4.0 matter, if
at all.

Alain
