DeleteSnapshotVhdSet	Deletes a snapshot from a VHD Set file.
DeleteVirtualDiskMetadata	Deletes metadata from a virtual disk.
DetachVirtualDisk	Detaches a virtual hard disk (VHD) or CD or DVD image file (ISO) by locating an appropriate virtual disk provider to accomplish the operation.
EnumerateVirtualDiskMetadata	Enumerates the metadata associated with a virtual disk.
ExpandVirtualDisk	Increases the size of a fixed or dynamically expandable virtual hard disk (VHD).
GetStorageDependencyInformation	Returns the relationships between virtual hard disks (VHDs) or CD or DVD image file (ISO) or the volumes contained within those disks and their parent disk or volume.
