Question: Deduplication App?
I have two 4TB hard drives with 3 or 4 folders (500Gb +/-) which are copies of each other. Some of the folders have newer files in them. Is there a deduplication app or software that can compare these 3/4 folders and move all those files and folders into 1 folder with only the most recent of up-to-date files?
