Then, choose the location to check (it can be the entire system or particular folder only). Once again, this method is not really convenient as you have to guess how certain files are named and in what shape you used to save them.

Stage 4: You will see a pop-up window on the screen. Just move on by clicking Next. It will take you to iPhoto Library to start the procedure of scanning.

Stage 5: Pick the corresponding Library and go to Select Library to Scan Duplicates. The process of identification may take up to several minutes. It all depends on how many photos and of which size you wish to scan.
