DiskDup 2.9.2 - Popular Pick Clean

DiskDup+ will allow you to duplicate floppy disks quickly
and easily.
It has been designed to create complete sector by sector copies
of a cartridge in the same way that it duplicates floppies. When a
"Master" cartridge is inserted, DiskDup Pro notes the size of the
cartridge and determines the number of swaps necessary to complete the
copy. A 100 Megabyte cartridge, for example, would require 4 swaps if
there were 5 Megabytes of internal RAM plus 20 Megabytes of free disk
space on all other mounted disk volumes.
