When compacting and repairing a database, Access doesn't actually compact the current copy of the database, it just saves it as db1.mdb? Am I correct?

If so:

I am building an application which there will not be an admin present to compact and repair. I am using a function to this automatically at program start. How would I go about replacing the current copy of the application with the compacted one?
