No problem, man. Thought I'd share my experience here, incase someone else ran into the same problem that I did (Which, if they have Vista, they probably will). Glad I found the WinRAR trick, because trying to do command-prompt stuff makes me feel like a complete dribbling idiot. For some reason, I just can't master the syntax.
EDIT: I see where you've added to the top post, but make sure to add that you MUST add the folder to an archive, *then* select "Delete files after archiving" to get rid of it, otherwise the trick won't work. Also, I've only tested it in WinRAR, not WinZip, but it should work as long as there's an option to delete after archiving.
