.VMDK File Extension

There is only one file type that uses the .VMDK extension:

Virtual Machine Disk File

Virtual Machine Disk File

Virtual disk that stores the contents of a VMware virtual machine hard disk; can be accessed as a physical hard disk with VMware software; typically named "[vmname].vmdk;" may be set at a fixed size or configured to grow over time using VMware's Virtual Disk Manager.

Other files that make up a virtual disk may include:

  • [vmname]-s[###].vmdk - for split virtual disk files.
  • [vmname]-f[###].vmdk - for split files with disk space allocated in advance.
  • [diskname]-[###].vmdk - stores changes made to a virtual disk.
Early versions of VMware software used the .DSK extension for virtual disk files.

VMDK files are used by VMware software, but can also be mounted as a virtual disk using WinMount. Once the VMDK file has been mounted with WinMount, users can delete, copy, and modify files in the virtual disk.
