Surely it would be simpler to store all this info in a database table? e.g.
id : int created : timestamp filename : varchar Only files that actually existed would be in the DB, plus you could do all your sorting on the 'created' timestamp column. Querying the DB should be much simpler and more efficient than using the filesystem. Aside from anything else, it would make your program a lot easier to understand to anyone having to maintain it in the future.
