I'm after permanent files with unique and sequential file names.
Then enforce that by storing a sequence number somewhere, permanently. Make all programs that create files in that directory, use it.

Think of an autoincrement field in a database (why not use that? SQLite might be a decent and fast solution), or a setup with a little file holding the number, pretty much like the "web access counters" of a decade ago.
