I believe there should be a space between the command (deltree) and the option (/y)
But like someone else said - be carefully when using the deltree option (Delete Tree) - it will wipe out everything in there, and if you do it wrong (like hit enter after the /y, before you type in "temp"), you could easly wipe our your hard drive. :-)
