Before actually converting or enabling older files, it would be good to know how to work with the various file types in Access 2007. A good place to start is to specify the default file format. And, since we all agree that the data should not be in the front-end or application file, we'll also tell you how to split the database.

It is easy to set the default file format. And, if you need to specify a different file type, it takes only a couple of extra clicks to override the default selection.
Setting the default file format is accomplished in a few easy steps.
