The vhd file extension is associated with Virtual Hard Disk. A disk image for Microsoft Virtual Server. Microsoft has set the Virtual Hard Disk (VHD) file format as the standard for running and managing virtual machines using Microsoft Virtual Server 2005.
The VHD file format provides for a range of disk types, including dynamically expanding, linked, undo, and differencing disks.
The Virtual Hard Disk (VHD) format is a publicly-available image format specification that allows encapsulation of the hard disk into an individual file for use by the operating system as a virtual disk in all the same ways physical hard disks are used.
These virtual disks are capable of hosting native file systems (NTFS, FAT, exFAT, and UDFS) while supporting standard disk and file operations. VHD API support allows management of the virtual disks. Virtual disks created with the VHD API can function as boot disks.
The vhd file extension is also associated with Windows Vista complete PC backups.
