I have Created a path for Library Manager that works for moving content

By creating a Steinberg/Cubase/Nuendo folder and choosing that path repeatedly.
Each VSTi gets its own folder (example Halion, Groove Agent etc). It has to be done logically with patience and is a process that can take time. I will follow up with results and any problems.
