Although Easeus partition master v7.0.1 Pro allow the user to view the contents of a partition of a hidden partition or a partition that has no drive letter assigned to it, Easeus Partition master v7.0.1 Pro and previous releases DOES NOT ALLOW the USER to copy (from) selected files/folders from the hidden or non-drive-letered partition.
Which invariably means I prefer to use either: Acronis DiskDirector Suite which does allow the Copy from Explore function, or, Paragon Partition Manager.
