Frequently asked questions

What is a .vmdk file?

VMware's virtual hard disk format, storing the entire virtual disk contents of a virtual machine.

Can I edit a .vmdk file?

Not directly as text — .vmdk is a runnable or packaged format, not one meant for manual editing.

Does having a .vmdk extension mean the file is safe?

No single extension can guarantee that. Virtual machine files can contain an entire guest operating system, including any software installed on it. Only import VM images from sources you trust. Always consider where the file came from, not just its name.
