That's not really a flat-file database, more of a bunch of
sequentially-numbered files. For it to be a database, you'd have to have a
way of looking up the contents of the files in a useful fashion (dredging
through a directory of files is not exactly useful).
May I enquire as to why you aren't using a more traditional database?
