It would be great if you could designate where Audacity looks for VST’S in Windows. For instance, another drive on your PC. Or a dedicated folder by the user! Thank you for your consideration. Have a great day all.
I think this is largely beyond what a VST host program (such as Audacity) should do.
Steinberg (who created the VST specification) published an article relating to this: https://helpcenter.steinberg.de/hc/en-us/articles/115000177084-VST-plug-in-locations-on-Windows
