Norton was always a PC company — Norton Commander, the file manager that launched a thousand clones, was only ever available for DOS, like the rest of the company’s offerings in those days. If they’d decided to port it to the C64, though, it would likely look a lot like [retro3872809] aka [Chicken 64]’s Multi Floppy Commander with Turbo, available on GitLab.
As you might be able to see on the screen shot above or in the demo video below, the application provides an 80-column interface with a split view to show a pair of floppies side-by-side. Not that you’re limited to two floppies, however. The software is happy to swap between all the drives on the bus, to the C64’s maximum of four. All four drives will be usable since the file manager lives on a cartridge.All drive models are supported, though not all have turbo. As a file manager, it looks like it has the normal functionality you’d expect: renaming, copying, moving and deleting files and directories. You can also launch programs or print disk listings, assuming you have a printer attached to your Commodore.
Said Commodore perhaps needn’t be vintage, as they’re selling new ones again, but if you want a disk drive you may have to fix it yourself.
