Is there an API or a simple way to check if a volume is deduped on Windows server 2012?

Question

Here's the MSDN page about Data deduplication API, and it seems there's no API to check if a volume is deduped.

One way to do it is to check if there's a folder named "Dedup" under "System Volume Information", but I don't think it is reliable for every case.

Answer 1

The list of deduped volumes can be obtained in powershell. See the following link about a third of the way down the page
