Finally. For the first one I would just restart the VM, but the second just consumed my whole drive with no way to get it back. I had to resort to enabling filesystem compression on the vhd file.

Is this why the WindowsApp/Ubuntu folder was hitting upwards 70Gbs recently?

I never really paid attention to the size of the VHD, and assumed that I had somehow generated gigabytes of dist and node_modules.

Isn't this just an fstrim followed by Optimize-VHD to get the space back?
