The tool lets you scan your entire PC for files in multiple formats, sizes, paths, or according to dates. Sorting out music is also stated to be easy through the Audio Search settings that will let you compare various tags such as the artist, song name, album and many other attributes through formats like MP3, WMA, M4A, M4P, OGG, APE and FLAC.
