vhdxtool.exe VhxdTool is a command line utility for Windows for quick creation and resizing of virtual hard disk files (VHDX). VhdxTool offers similar functionality to a former program vhdtool for Windows Server 2008/R2, but while vhdtool worked with older (VHD) format, vhdxtool works with the new (VHDX) format.
Unlike standard Windows tools like diskpart or New-VHD, and like the former vhdtool for VHD files, this tool does not write the zeros in the newly created or enlarged VHDX file. Please make sure you understand the implications of this technique: more details in our
blog post.
