About VDI
VDI is VirtualBox's own disk, there since its first release by Innotek in 2007, and kept by Sun and then Oracle. Each machine you make in VirtualBox gets one, in its folder under VirtualBox VMs.
A dynamic VDI stores the disk in blocks of 1 MB, only once they're written, so it grows as the machine fills it. A fixed one keeps every block from the start. Inside is a whole disk: MBR or GPT, then NTFS for Windows, ext4 for Linux or APFS for macOS.
Filepeek reads it with 7-Zip compiled to WebAssembly and draws the disk as a map, each partition to scale with its file system and space used, its volumes as folders. Files open at once, and Windows' own files stay out of the way until you choose Show hidden files.

No browser opens a VDI: they download it. Filepeek opens it as a folder of its partitions in Chrome, Edge, Firefox and Safari.

Questions
How do I open a VDI without VirtualBox?
Drop it on this page or choose Peek a VDI. The disk shows as a map of its partitions, each volume as a folder, and the file you pick opens right away.
Can I get files out of a machine that won't start?
Yes. Open its VDI, find what you need, and save it as a ZIP or one file at a time. The disk itself is never changed.
Which file systems open?
NTFS, FAT, exFAT, ext2 to ext4, HFS+ and APFS, plus Linux LVM volumes. A partition locked with BitLocker shows as locked.
What about snapshots?
VirtualBox keeps a snapshot's changes in another VDI in the machine's Snapshots folder. The machine's main VDI opens as it was before them.
Is my VDI uploaded?
No. It opens inside your browser and never leaves your device, however big it is.
