Something is strange with Aminet. I've been using Multidos for many years and just went to verify it still on Aminet. There have only been 79 DLs? Hard to believe.
Anyway, Multidos will allow you to read, write, and format MS-dos 720K disks. It executes from the CLI and will integrate well into Dopus, Ordering, etc. It's very simple to use and it doesn't require you to leave an icon on Workbench while it's active.
Good Luck!
