VMDK is a file extension for virtual disk image files that are created by VMware products, such as VMware Workstation, VMware ESXi and other third-party tools. It is mostly used for cloud computing services and virtualization. A VMDK file contains all the info of a virtual machine. Usually, non-virtualized machines can only access individual system files and components, but a virtual disk file contains all the necessary information on a single disk, which enables it for independent operations.

However, it is recorded that many times when users want to access their VMDK file data, the virtual machine often stop working or doesn’t open VMDK file. There can be two possibilities behind this problem, either the VM is not compatible with your system or the VMDK file is corrupt.
