I have what I believe are duplicate photos that have ended up in 11 different folders across multiple drives. I am trying to get rid of many of the dups, but need to compare the photos quickly if possible to confirm I am not getting rid of items I should be keeping. I have looked at the online material for Aperature and Lightroom and am not sure if either of these will allow me to do this. I have been using finder but that is a painful process as I need to have 11 windows open and keep jumping back and forth between windows. There has to be a more efficient way to get through this. So, I am curious if either of the programs I mentioned would do the trick, or some other software? Programs like PSE really don't help for this. Adobe Bridge was somewhat useful but also needs multiple copies of the program running at the same time to use multiple folders. Appreciate any thoughts on this. Many of the folders are scrambled from moving things improperly from iPhoto (please don't ask - that's a whole story unto itself) and various computer crashes.
