Simplest (practical) file system?

Bob,

In "from scratch" projects I've done, I've always just implemented the
MS/PC-DOS FAT filesystem. It's simple, and it has the advantage of being
readable and writable from any regular desktop PC directly. I've also done
several variants of *nix filesystems, which are only slightly more complex,
but perform much better at the expense of a bit of RAM. Naturally, if you
stick to the standards, you'll have no trouble reading, writing (and
verifying the correctness of) these volumes from Linux or FreeBSD. I prefer
the former for floppies and other small-size removables, that latter for
hard disks.
