Disk the Masher system (.dms) was an often used method on
Amiga, to create a
compressed image of a discs (usually
floppy). The discs were read
block-by-block, and their data structure was maintained. The DMS won approval particularly in the
demo scene and the
Warez scene, since with this system disc images could generally be distributed easily in
mailbox networks like
FidoNet or via
telecommunications (
modems).
The DiskMasher format is copyright-protected and has problems storing particular sequences of bits due to bugs in the compression algorithm, but was widely used in the pirate and demo scenes.
