Enlarge a Virtual Disk in VirtualBox

I totally underestimated the size of my virtual disk when I created one and when I tried to increase it, I did not see anything in Settings that would allowed me to do some. In order to do that, you would actually need to use a command line.

Open terminal and change into directory where you have your Virtual box image.

$ cd VirtualBox\ VMs/MyDrive

then run following command

$ VBoxManage modifyhd MyDrive.vdi --resize 32768

0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100%

to increase MyDrive VM to 32GB of storage.

That's it!
