Doesn’t work for large collections of files - 100K+

I tried using this on an extrenal hard drive with 100K+ files. It got up to 159,353 files 2 separate times, and then stayed there. The “we’re not frozen…”, “still working on it…”, etc. progress messages still appeared and were chagning. But it would never get above that many files. Not sure why. Saw another review about this, and gave up. I kept the files pretty organized on my hard drive, so I was able to manually get rid of the duplicates pretty quickly (20ish minutes). Seems like a good app based on reviews, but didn’t work for me at all...
