Doesnt always find duplicates

Bought this to find duplicate photos on my disk. Unfortunately, while finding some duplicates, it missed most others. Specifically, if you have lots of subfolders on the left and one folder on the right, it doesnt pick up the duplicates in the subfolders, even if you check the box to tell it to also compare subfolders and limit the checking just to filename and size. Narrow down the left to one folder and it finds them--but that rather defeats the object…I want the app to find them in the first place!

Also crashed once.

Didnt try the editing feature on text files. Perhaps its good (hence 2 stars).
