What is a VHD file?
A VHD file contains a virtual hard disk image used by Microsoft Windows Virtual PC, a Windows virtualization program. It stores the contents of a hard disk of a virtual machine (VM), which may include disk partitions, a file system, files, and folders. VHD files may be used to install multiple operating systems on a single computer, test software programs, or run older applications.
The VHD Image Format Specification has been available as a royalty-free license since June, 2005. The VHDX format was introduced in 2012 as an extension of the VHD format. Virtual hard disks saved in the VHDX format are stored in .VHDX files.
How to open a VHD file
You can mount VHD files with various virtualization programs and launch the virtual machine they contain, including Microsoft File Explorer (bundled with Windows), VMWare Workstation (Windows, Linux), VMWare Fusion (Mac), and QEMU (cross-platform). For example, to mount a VHD file with Windows File Explorer, right-click the VHD file and select Mount.
You can also use 7-Zip (Windows) to examine a VHD file's contents without mounting it.

VHDL Source File

Source file written in VHDL, which stands for Very High Speed Integrated Circuits (VHSIC) Hardware Description Language (HDL); often used for automating the design of electrical circuits and components.
Electronic engineers can use VHDL to describe hardware components in a text-based format. This description can then be used to manufacture a physical circuit such as a motherboard, processor, or memory module.
