.VDI File Extension

A VDI file is a virtual disk image used by Oracle VM VirtualBox, an open-source desktop virtualization program. It is used to create a VirtualBox virtual machine. Virtual machines allow users to run additional operating systems and programs on their PCs.

Oracle VM VirtualBox is a free program that allows users to create and manage virtual machines. Many businesses use VirtualBox to allow their employees to run additional operating systems on their PCs. For example, a Mac user can use VirtualBox to run Windows on their Mac.

A VDI file is a disk image that a VirtualBox user can use to start a virtual machine. Continuing the example above, a user creating a Windows virtual machine could use a Windows VDI file as that machine's hard disk.

You can open a VDI file in Oracle VM VirtualBox (cross-platform) as part of creating a new virtual machine. To do so:

1. Place your VDI file in VirtualBox's HardDisks directory.
2. Open VirtualBox and create a new virtual machine that uses the same operating system as your VDI file.
3. When asked to provide a hard disk image, select Use existing hard disk. Then, select the folder icon.
4. In the Virtual Media Manager window, select Add. Then, select your VDI file.
5. Finish creating your virtual machine.
