Basically, a Virtual Hard Disk (VHD) is a file format that contains structures that are “exactly” identical to the structure of a hard drive. It can be understood as a virtual hard disk located on a native file system and “packaged” in a single file.
VHD is used to store virtual operating systems, related programs and acts like a real hard drive.
Just like Windows 7, on Windows 10 you can easily create a virtual hard disk without installing or using any tools.
