Media Catalog Studio investigates your multimedia collection and saves every bit of important information about it. Then you can use this information to eliminate duplicates, to search for some particular file or for a certain line of lyrics, to create and print reports. However, one of the most important features of this program is the ability to build custom views. It's up to you how your MP3, WMA, WAV, AVI, and other files will be listed. Sort them by title, artist, owner etc.
