DOS 3.3 used to have DiskCopy utility to copy floppies and files from disk to disk, and one called "Muffin" used to copy "copy protected" floppies onto other floppies by recreating the errors on the media as best as possible. It could copy almost anything (from floppy to floppy)! But DiskCopy would be better if you were copying to a hard drive, lets say. "Copy Protected" stuff you are stuck with the media you have unless you went in with a sector editor and disassembler and hacked out the protection codes from the programs, and then you can file copy the disk.
