What is a .VHDX file?
VHDX is Microsoft’s newer virtual hard disk, supporting much larger sizes. Created by Hyper-V.
- Did you know
- VHDX is the Hyper-V virtual-disk format introduced with Windows Server 2012, supporting far larger disks than VHD.
- VHDX keeps a metadata log so an interrupted write can be replayed and the disk recovered intact after a power failure, unlike the older VHD.
- VHDX is optimised for 4 KB sector drives, with large block sizes that reduce I/O overhead on modern storage.
- What Analyser reads
- Identify disk and virtual-machine images: ISO, VHD/VHDX (Hyper-V), VMDK (VMware), QCOW2 (QEMU), and VDI (VirtualBox). For raw IMG images it decodes the partition table (MBR/GPT) and the first volume's filesystem - FAT16/32, NTFS, exFAT - with label, cluster size, and volume size.
- Depth of analysis
- .VHDX is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .VHDX file
- Drag a .VHDX file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
