Tip of the Day: Un-dedup'ing


Today’s Tip…

Question: On Windows Server 2012 or newer, if I have a NTFS deduplicated volume and need to ‘un-dedup’ a certain folder, how do I accomplish this?

Answer: You can use the Expand-DedupFile cmdlet in Windows PowerShell.

dir g:\folder1 | expand-dedupfile

NOTE:  This will simply ‘Un-duplicate’ the folder.  To keep it in this expanded form, you will need to add it to dedup’s exclusion list.
