Frequently asked questions

What is a .vdi file?

Oracle VirtualBox's native virtual hard disk format.

Can I edit a .vdi file?

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

Does having a .vdi 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.
