This guide provides simple steps to open VDI files on Windows 10 using VirtualBox, a popular virtualization software. VDI (Virtual Disk Image) files store virtual disk content and can be used across various operating systems. To manually open a VDI file, copy it to the Virtual Hard Disk folder, create a new virtual machine in VirtualBox, and select the VDI file from the Virtual Media Manager. If you encounter corrupted VDI files, consider using a specialized tool like the DRS VDI Recovery Tool, which can recover and restore damaged files efficiently.
