I've seen some Java apps that use the FS as the DB. Nothing wrong with
that. I think an FS can be quite a good DB, if implemented well. This gives
many data manipulation options with traditional FS tools, shell
scripts, etc.

Large Maildirs for postfix and qmail/Courier. Some people don't delete
email at all.
