Frequently asked questions

What is a .vhd file?

Microsoft's virtual hard disk format, used by Hyper-V and also supported by Windows' native disk mounting tools.

Can I edit a .vhd file?

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

Does having a .vhd 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.
