sorry if this has been posted before, I couldn't find the exact same question. Closest is probably https://ghisler.ch/board/viewtopic.php?t=52595. Maybe it already answers my questions, but I don't understand it that way, yet.
What I have:
Two folders, one - FolderA - containing hundreds of pictures in high quality. The other one - FolderB - containing a subset (~50) of the pictures in FolderA, but in worse quality. However, the filenames are the same in both folders.
What I want to do:
I want to get the subset from FolderB, but in high quality from FolderA. In other words, I want to find the pictures listed in FolderB in FolderA and copy those to a new FolderC.
Can somebody tell me, if that's possible straight forward? If so, can you give me a dummy explanation, please?

Thanks,
arbine
