WTware RDP client

http://wtware.com/docs5/sound.html

Not understand about folder access. Which folder?

I have configured WTWare Server with RaspberryPi 3b+ client.

I am able to login at the client, run applications independently, browse internet etc. But while playing Youtube videos, Only Video is seen, NO Audio. How to get Audio locally at the client, independently..?

Also, how can we assign individual folder access permissions for each client in the server?
