The Update Media Count tool tells you how many tests use each Media file in your database, by updating the Usage field for each Media file. To view the Usage field, highlight TG Question Bank > Picture Warehouse, Sound Warehouse, or Movie Warehouse > Media file.
Before deleting a Media file from your database, you should use the Update Media Count tool to verify it is not in use by any test questions.
To update the media count for your database, Select Tools > Update Media Count in the Test Generator main window.
