Let’s first talk about VHD file. VHD file is mainly used as the hard disk drive of a virtual machine. It’s just like a normal hard disk used by your computer system for storing the entire content within a single file. It has the similar functionalities as a typical physical hard drive, but it can only be accessed managed and installed on a virtual machine. It contains the same hard drive sectors which are found on a physical hard drive which include disk partitions and a file system. Also, it may contain files and folders. Though a VHD file is created on a physical hard drive of your computer, but it has a logical distribution of its own.
The disk size of a VHD file can either be static (fixed) or flexible (dynamic). Whenever a virtual hard disk is created, a particular size is allocated. If you create a fixed virtual hard disk of 100 GB, the entire allocated disk space is taken up on the host machine. But if you create a dynamic (expandable) virtual disk, unlike fixed disk type, it only takes a tiny amount of space. It grows time by time as data is added to it.
VHD file is also commonly known as the backup created by Windows Vista and its later versions. In these Windows versions, Backup and Restore is the built-in tool used for backing up the computer data. If you are taking files backup, they are saved into ZIP archives. And if you are creating a Windows system image as backup, it is saved into a VHD file. In this way, a VHD file is also used a backup file in Windows Vista and its later versions.
