Awesome App!!

This is a fantastic app. Upgraded to the Pro version after trialling the free one. Worth every cent. Used it to bring order out of chaos from my combined documents, music, photo and video libraries that were merged from various depositories. Worked through some 40,000+ files with ease. Thank you developer!!!
