If you know where the VSTs are just add their location to the VST location in Studio One, there's no need to relocate them. I was explaining the easiest way to find the VST's location on your drive, in case you didn't know where they were. Then in Studio One, choose Studio One > Options > Locations > VST Locations and Add the location of the VST's. There is no need to move them. You just need to show Studio One where to look for them.
