There are different ways to display the databases in the database window. This is how they look using the large symbols.

 

 

You are shown more information if you display the databases in the Details view.

 

 

The column Usage shows how often you have opened the database. The column Created shows the creation date of the databases, which you might want to use for sorting the list.

 

 

Note: The program removes database symbols if a database has not been used for a long time. The database is still available on your hard drive and will be displayed if you load it again.
