When trying to delete File or Folder on Microsoft Hyper-v CSV Volume you can get errors like :
Access Denied OR You do not have Permission to access this folder or file !
This can happens if you are trying to delete them from the wrong server on the cluster which is not the owner of the CSV , you need to open the :
"Failover Cluster Manager" -> go to "Storage" -> "Disks" -> Then check which server is the owner of the volume
Then logon to this server and try the operation from there again.
