Is this only compatible with FAT32, or is it also compatible with FAT12/16? It would be very cool if this would support floppy disks.

Regarding the format, once you convert it, does the target device need to have a driver to support the format? It mentions that this would allow for > 4GB files for TVs, but these are typically non-updated very out of date OSes.

I think MS missed a trick by not making the boot sector also contain a simplistic driver, although it would have been a push to keep it all down at 512 bytes.

It's simple enough to work on basically anything, but for what purpose?

The max file size on FAT12/16 is the same as the max drive size.

And FAT32 is very easy to implement for any system dealing with multiple megabytes.

As I replied to the comment, it's about having a filesystem that scales from floppy disks to hard drives. This is quite important for hobby OSes.
How do you get files > 4 GiB on a floppy disk?
You don't of course, it's about having a filesystem that works from floppy disk all the way to hard drive.
