There is no maximum size of either file. It would be strictly dependent on the memory you have available.
Well, you could say there is a mximum, in terms of addressable memory. Since your computer will be able to use 64 bit addressing, that limit of 2^64 is far larger than any amount of memory you can put in your computer, or on your drive. So effectively, the limit is the available memory you have on your computer, and the memory you have on your drive.
