I understand the trepidation. Maybe try moving just one (or a few even) files. Or even copying them so they remain in the original location too? Note which ones you’ve moved then if you get an error message you can either point at the new location or move the file(s) back? Alternatively you might find having moved one you find the related sounds?
You could also try renaming the GA folder to see if that generates an error…
These are things I’d try, obviously if you’re not at all confident in what might happen then, don’t!
