Finally!
I have been to busy to hunt down a good app to delete my duplicates. Bouncing between software and with the camera always resetting to zero duplicates were all over. I have just ran this app for a few of my shoots and just like that its 8gbs smaller. best on byte to byte if you do studio work because sometimes the model doesnt move enough for the other filters to see and there is more weeding that needs to happen for a safe deletion.
Great app well worth the $9.99
