virtualbox.org

Dear Concern,
I recently installed VirtualBox in my laptop which runs windows 10. While installing virtualbox I allocated about 30gb space for creating virtaul hard disk. I installed Oracle Linux on that Virtual Disk. For some reason I had to remove the Oracle linux from that Virtual Disk. Unfortunately while removing Oracle linux I forgot to remove the storage space allocated.Now I have lost about 20gb space after this.

Is there any way to recover my lost disk space? Eagerly waiting for your reply.

Thank you.

Regards

Of course there is. Just find the virtual disk file and delete it. If you created it you should know what it was called.

VM is not dual boot. A virtual machine's "drives" are just files on the host, not partitions that need special treatment. Normally when you unregister a VM VirtualBox asks you if you want to delete those physical files also. I guess you must have answered no. No matter, you can delete them manually.

You can find your VM folders in your C:\<user documents>\VirtualBox VMs\ folder. Each folder contains the file set for one VM.

I have same problem.
I uninstall app but I forgot to delete virtual machine and I lost about 50GB memory (in that virtual machine where i had allocated to).
I tryed to fix it but it's don't help.

And i don't find that folder.

Can someone help? thanks in advance

There is nothing special about the vm files. As long as you can remember what you called the vm, just search your hard disk for that name. If you can't remember its name, search for a file with the extension .vdi . That should find the virtual hard disk, which will be most of that 50G. If that file is in a folder with the vm's name, delete the whole folder.The contents of the folder should look something like the attached screenshot.

There are also free tools that let you identify the largest files on your PC. That would very quickly show you where the VDI files are.

Ok thanks i'll do it
