Hi,
the little file with the lock system is automatically created when u open an access database, it contains user, locking, ... information about the cutrrent database. This has been so since Access 2.0.
Some things you can try to speed it up:
- compact/repair the database
- If the database is a front end/back-end application? Then you can check the connection speed to the back-end database
- convert to 2007 file format
- make a new database and import all objects from the old database in the new one.
hope one of these helps
