Notes about the VDI file extension:



Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.

The VDI file type is primarily associated with 'VirtualBox' by innotek GmbH. innotek VirtualBox is a general-purpose full virtualizer for x86 hardware. Targeted at server, desktop and embedded use, it is now the only professional-quality virtualization solution that is also Open Source Software. It allows you run an operating system inside another operating system's window (e.g. run FreeBSD in a Linux window). The VDI files reside on the host system and are seen by the guest systems as hard disks of a certain geometry.
