I was helping a friend by reformatting his pc and reinstalling windows because it was slow, when I was downloading the drivers for it on my MacBook Pro (didn't have access to the router since it's downstairs and his pc didn't have a wireless card), it downloaded a folder filled with locked files, it comes several folders deep and all of the files are locked, fun. So I tried to delete it using sudo rm -r, but it says I don't have sufficient privileges, anyone know a command I can use to delete it all? I'd rather not do it by hand, that'd take forever.
