I know it's off topic but if you know what "wheel" is I wouldn't mind knowing...
wheel (as in "big wheel", aka "big shot", etc) is for trusted users. Various systems use it in different ways, but it's an elevated level of privs for trusted users, sort of a coarse grained "sudoers" method that was created before sudo came to be.
Also should i be deleting the lock folder, since it's empty?
no, because then it wouldn't exist for apps to create lock files in anymore...
