There is a wizard to find image pairs - it groups image files in the same folder with the same name (but different file ext).
This could be useful in your case. It's called - "fast find image file pairs"
Note it doesn't compare by content at all - just by the name.

It should be OK - the program just reads the file as a stream of bytes (assuming you are hashing). It doesn't execute the file.

Thanks for posting the story A few notes- -Duplicate Cleaner 5 now has an option (on the scan tab) to prevent the computer from sleeping during a long scan. -V5.21 will now alert you to check the log when files/folders have been skipped during the scan (Either due to errors or user settings) -Adding...

One thing that may help is turning on the Toolbar (settings). You'll then get a Scan button you can access from any tab.

Will check - I haven't managed to reproduce the F6 error so far. Will need to look at the code...

The thumbnail view is a bit of a hack and I'd like to improve the navigation if I can.

Check the log file - this should list all skipped / errored files and folders.

Not sure of a program to test access to everything, sorry.

Thanks, confirmed bug - will fix in next update.

Thanks for the feedback
In thumb view, scrolling to found files is broken a can't be fixed currently (will remove option). However, 'use as filter' does work well here (as in the other modes).

Looking into this - seems there is a problem storing the column size when it is resized by double-clicking

This would be super rare to have an MD5 collision in a normal fileset. I do have a couple of jpgs with different pictures within and the same MD5. They were deliberately created using a supercomputer though!
