You're doing a lot of work involving flat-file storage of sequential
data. There are two possibilities:

1) Your files are small, so you shouldn't concern yourself with
details at all - just do whatever looks reasonable, nothing will
matter; or
2) Your files are bigger than that, performance might be a problem
(especially when your Big Oh starts looking bad), and you should move
to a database.

Maybe even with small files, a database would be cleaner. You can grab
whichever rows you want based on their IDs, and the database will do
the work for you. Grab SQLite3 or PostgreSQL, give it a whirl - you
may find that it does everything you need, right out of the box.
