Ok, I am logged in as a root. I want to delete an empty folder calle "h". It was a test user. It's in the trash, but i want to empty the trash. I cant. They say i dont have permissions to do so. So I search for topics about this and not ONE has helped me since I tried all the codes in the terminal app and it didnt work. They did trash other files in my trash, but not this one. Then i downloaded BatChmod, and that didnt work either. Im getting a bit frustrated with with this problem since you could compare it to an itch and you cant scratch it.
