when I change the sort order AFTER it has found duplicates, the "marked" files remain the same, and the program finds files which are not 100% name matching as well, which makes my 10,000 file cleanup job impossible.
Thanks though. Still excited about the photo-resizing feature I used last night for the first-time, so I'll be alright.
If you change the sort order click the Select button to re-do the selection. (Or just run the dupe finder again.)
What do you mean by it not finding things which aren't 100% the same name? That should not be possible if you've configured it to search by name. Can you give an example?
My guess is that the files in the second screenshot are duplicates but the things they are duplicates of are hidden by your configuration. For example, if your window isn't set to show Hidden (or System-Hidden) files and the duplicates have those attributes set then you won't see them.
