How do I find and erase duplicated thumbnails in Aperture?
I currently use Aperture 3. Prior to using Aperture 3 I was using Iphoto and Iphoto unfortunately managed to duplicate photos by creating thumbnails 2 and even 3 or 4 times over. This happened a couple of years ago and thus I cannot revert to a prior library. For the past few years I was hoping apple would come up with a solution to this glitch. Perhaps a simple software update, an app, etc. Nothing yet.
Anyways, is there a way to find and delete these duplicated thumbnails in a time effective fashion? I have around 38,000 photos to sort through. I have used Duplicate Annihilator and it does not recognize the duplicated thumbnails as duplicates. I think this is due to their much smaller size. Also, what is the proper way of deleting the thumbnail duplicate? Do I delete it using just the "Delete Version" option orr do I delete the "Delete Master Image and All Versions" because I am not sure what is deemed appropriate and safe.
Finally, would it be easier to just purchase a cheap PC and have the programs available on a PC sort out this issue? It has been a long time and I have yet to discover that apple has found a suitable solution to this issue.
