Virtual Hard Disk
VHD is a file format that represents a virtual hard disk drive (HDD). They can contain
what is found on a physical HDD, such as disk partitions and a file system, which in turn
can contain files and folders. They are normally used as the hard disk of a virtual machine
(VM). They are the native file format for Microsoft's hypervisor (virtual machine system), Hyper-V.
