What is a .VMDK file?
VMDK is VMware’s virtual hard disk format. Created and opened by VMware.
- Did you know
- VMDK is the virtual-disk format of VMware, the company that popularised x86 virtualisation.
- A VMDK can consist of a small text descriptor plus one or more data extents, each markable as read-write, read-only or no-access.
- VMware opened the VMDK specification with revision 5.0 in 2011, and it is one of the disk formats used inside the Open Virtualization Format.
- 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
- .VMDK 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 .VMDK file
- Drag a .VMDK 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.
