What is .VHD File Extension?

There are mainly two types of .vhd files, one is used for virtual hard disks and another is in Quartus II VHDL Design File. So read detailed information about both of VHD files to learn everything about the particular file type.

  1. .VHD- Virtual Hard Disk File

The .vhd file extension is a Windows backup file primary associated with Windows Vista and also used by a Windows virtual server to backup complete PC in a single disk image. A VHD type file is also known as image-based backup file which can be used to backup and restore your whole PC environment such as: operating system, user settings, installed programs, and data files, etc. These virtual disks are proficient of presenting native file systems (NTFS, FAT, exFAT, and UDFS) while supporting standard disk & file operations.

VHD (Virtual Hard Disk) format of the file is used for Microsoft Windows Virtual PC that works as an individual hard disk. Where Windows XP uses BKF file to backup Windows PC and Win 7 has option to create .bkf or .vhd for backup files. We hope now you will able to understand what is VHD file format and for what purpose it is used. Keep reading for more details.

What is the Basic Structure of VHD File Extension?

A virtual hard disk (.VHD) is a file that captures a hard disk image for holding complete PC backup. VHD files may be used to test software programs, install multiple OS on a single PC, or run older applications. You can view or read a VHD file binary structure by opening the file with Editplus program. To check more details about the VHD file structure reads a blog.

Brief Information of VHDL Design File!

The VHD file extension is also used by the Quartus II design software. VHDL files stand for Very High Speed Integrated Circuits (VHSIC). This file is a text file generally used for automating the design of electrical circuits and components. Quartus II replaces the MAX+PLUS II Software for chip design. So VHD files were also used by MAX+PLUS application.
