How come I can't erase a folder. What am I doing wrong?

What exactly do you do when trying to erase it?

k heres an answer that might work but as peerless is saying give more info were not spychic.

or download PCBug Doctor
if you are trying to delete any limewire applications don't cause you'll be screwed forever, tell us if you need to uninstall limewire

Im psychic so I know! Sometimes a download cant be deleted because: "That progarm its being used by anthor person or progarm" Even if its not being used by limewire/lan/yourself

just rebooting somehow fixs that

I would also like to know how to delete folders. I made a few folders ( under shared..etc.) not to mention that when i downloaded a nero program one just showed up. i would just like to deleted the 5 folders i accidently created. I think that is as much info as i have. thanks a bunch

I actully ment delinvfile instead of pc bug doctor it deletes anything just make shure not to accidently delete windows or you'll be swearing alot and you won't get the blue screen of death but the screan of nothingness

ps I'm a little hipper for some reason now so don't mind my stupidness like the screen of nothingness. lol
