How effective would the files be if I were to listen in my sleep?

Would listening to a file more than once in a single day compound the effectiveness of it?

Listening to them while you sleep may work fine for you, but that depends almost entirely on the person. I know people who have had great success doing that, and people who have had none.

Listening to a file more than once per day, however, should make it work faster. But again that's depending on the person, but I'd say that stands a fairly good chance of working like that with most people, assuming that they are not one of those oh so rare freaks that can't be put under. :P
