My brother dragged some of his stuff from his harddrive onto my mac. When I tried to delete em, I get the "fdksfsd.smc" is locked. Now it's permanently on my computer. How do I delete this? I tried to cut the thing into my "Windows" partition and boot up windows to delete em (figger that it could work like that) but THERE ISN'T A WAY to CUT the folder!! How do I get rid of these "locked" files? It's taking up 10gigs of my space!!
