VHD Tool

Build Status

This utility provides VHD / VHDX (un-)mount support using the Microsoft (c) virtual-disk API. It's meant as fast replacement for DiskPart providing the same functionality. Using diskpart (un-)mounting disk images took (Windows 7 / 8.1) a lot of time ~1 sec per file. So i wrote this small utility to make (un-)mounting faster.

Build Requirements

  • Visual Studio
  • C++11
  • Boost library
