vhdxtool.exe

VhxdTool is a command line utility for Windows for rapid creation and resizing of virtual disk files (VHDX). VhdxTool provides similar functionality to a former utility vhdtool for Windows Server 2008/R2, but whereas vhdtool worked with older (VHD) format, VhdxTool works with the new (VHDX) format.

Unlike Windows standard tools such as diskpart or New-VHD, and like a former vhdtool for VHD-files, this tool does not zero-out the newly created or resized VHDX-file. Please make sure you understand the implications of this technique as outlined in our blog-post.
