VirtualBox: Resizing Disks

 I once found myself needing to increase the size of a virtualbox disk. To that end, I found this guide helpful. Hence, making a note here:

Quick Tips:

1. This will only work on Dynamically Allocated Disks. It will NOT work on fixed disks.

2. Put .\ in front of the command vboxmanage.exe

Sample Command:

.\vboxmanage.exe modifymedium "C:\Users\David\VirtualBox VMs\Ubuntu2019\VirtSSD.vhd" --resize 30999
