I have two USB HDD drives. There is a lot of photos on them. Mostly, those are the same photos, but saved from my computer at different times. Directory structure is a mess.
Is there any app to compare these drives, move files so that directory trees are identical, and copy files from A to B and from B to A so each drive would have a full data set?
Names of files should be identical on both drives, but may repeat in different folders, for example
Note, that I prefer Windows software, but bootable USB would also be acceptable.
