Move VTRoot

I’m using CIS 8.2 Is it possible to change the location of the VTRoot folder? It has grown quite large and so takes disproportionate space on the SSD. I am also interested in what is stored here. Is it correct that applications here will have to be moved if I disable the Sandbox?

No you can’t choose location for VTRoot folder, user reset sandbox to clear out the sandbox. If you have applications installed inside the sandbox that you want to keep then you need to install on real system outside the sandbox.
