Hi, I hope I can get some help. I have a Lacie 2big thunderbolt 2 set as Raid 1. I’ve just completed the backup of almost 6TB of data (mainly pics), however half of it are just the mirror copies. Now I would move the original half on another disk, the problem is that the backup isn’t like sort out in different folders, it’s just every file and its copy back to back in sequence all together (file A, file A-2 , file B, file B-2, file C, file C - 2 etc.). So here is my question, how I select just one half of the files to move it in the new disk without their duplicate?
