Does everything except what I need - copying of only reference files

[SimonGoodwin]

Thanks for dupe guru. I'm trying to use it to compile a set of unique files from several SD card images, most of which (many thousands) are duplicates. I can find many options to copy or delete the dupes, but not what I need to create a new master SD, which is a copy of ONLY the non-duplicate files, in a single new directory. Am I missing something, or is this a new feature request?

I have tried to select all the dupes (OK) and toggle selection hoping to isolate only those 'reference' files but as they cannot be selected - not even for copying! I can understand why selection for deletion is unsafe - toggling hides everything.

Copy unselected or copy reference would meet my need.

So this is a workaround, but how about selecting the ones that you do not want as references and then copying the original files, which now show as dupes?

Be careful with this, as you are selecting the reference files as dupes, which is dangerous as it can delete the original files.

I repeat, be very careful. First, do a test with some files to get the hang of it.
