This should work. I'm not a Windows expert, but perhaps you can do it in a DOS window with "move" or "rename".
Are you moving the data across qtrees? In this case, you are stuck with copy-then-delete. Of course, you can cut down on the total disk space required by moving the 6T in smaller pieces.
Hi Stephen,
I want to move the data between subdirectories in the same qtree, volume, directory. On a windows server a move between different drive letters results in a copy+delete chain. But a move in the same drive letter results in not copying any data block. That´s what I wanted.
And even more, between drive letters the data would gain the security of the target drive letter, as ist is true for a copy in the same drive letter. But a move in the same drive letter does noch touch the data and does not touch the ACLs.
Kind regards Knut
