Add code to access both drives on dual disk-drive devices, different logical units on Lt. Kernal and Rear Admiral hard-drives, and different partitions on Creative Micro Designs drives (and their heirs, such as IDE64 and sd2iec). The program will be able to copy files between two file-systems on the same device. It should be able to read a CMD disk-emulation partition, and create an image on a bigger partition (and, go in the opposite direction, too).
(Sub-directory path support might be added during a later upgrade.)
