With Disk Charmer, you can free trapped Megabytes by setting the minimum allocation block size with the MacOS Extended format (HFS Plus); some companies charge thirty bucks just for this. You can also create oversized disks by reducing catalog space (you gain 9K on 800K disks, 19K on 1.4M disks, 1.5M on Zip disks and 2.1M on MO230 disks) The program also lets you: Initialize floppy disks in the background Copy floppy disks Verify floppy disk media Create DiskCopy disk images from floppies Recreate floppies from DiskCopy or DiskDup + disk images
