If a database is stored on a CD-ROM, it cannot be deleted in the conventional sense, but rather has to be unregistered. A CD database should always be unregistered before removing/disconnecting the storage medium it is on.

To unregister a CD database

1. Select the CD database that you want to unregister and choose Unregister CD Database from the context menu. The Confirm Unregister CD Database page appears.

   

2. Choose OK to unregister the CD database.
