Happily Amazed!
I took on the job of taking all archived photos on various forms of media from members of our family (my wife and I, kids and grandkids), copying them to my iMac, sorting out the duplicates and then making a copy of the combined archive for everybody. Since I still had hard copies of everything I decided to be reckless, let it search for, auto select and permanently delete all the duplicates. It took almost 1 1/2 hrs to do the job, but the result was more than satisfying. It went through a total of 430GB of mostly high resolution photo files, weeded out almost 10,000 duplicates, leaving me with 12,000 photos to sort into various folders, copy and distribute to everybody. I can’t even fathom the amount of time I saved over going through all those files manually and getting rid of the duplicates. We have not noticed any photos that went missing. Good job.
