I want to email a folder to a friend. But attachments (at least on gmail) can only take the form of a file type. So I guess the logical conclusion would be to "contract (or whatever you call it) the files", send them as that one "contraction (.rar, .zip, or w/e)," so then he can extract it and I won't have to send the files individually (there are many). But how do I do this? And is there an easier way?
