I created a VM using Virtual Box, but I gave it 25 GB, and I had 15 GB free. So I deleted it, and soon, uninstalled Virtual Box, but when I open my filesystem's properties, it is full, I mean to say about 80% of it is still in use, and the vdi file isn't anywhere. How do I free it up?

  • That is why in the future, always use dynamic disk allocation. Feb 25, 2016 at 10:49
  • What does df -h show?

  • You say you "deleted it" before uninstalling VB. What does this mean? Feb 25, 2016 at 12:27
  • I deleted the Virtual Machine only (not the VDI), then uninstalled Virtual Box.

By default your VirtualBox files should be located in $HOME/VirtualBox VMs/ so if you navigate there you should easily see if there are any remaining .vdi files still in place.

If your files were in a non-default location try running the following in a Terminal window to find them:

find $HOME -iname *.vdi

And when you find the files you can manually delete them...


  • I've tried that before asking that question, I think it damaged my filesystem, because it must've tried to allocate 25GB, while I had only 15 GB free.

  • So the find command had no results?

  • ext4 is quite robust, it doesn't get damaged because of trying to allocate more space than it has available. Feb 26, 2016 at 7:37

Uninstall VirtualBox:

sudo apt-get remove --purge virtualbox

Remove all settings:

sudo rm ~/.config/VirtualBox/ -Rf
