It may sound like a weird question. If I had a wii U I would have tested it out, but I'm waiting till the 26th to obtain mine. Anyway so Wii U USB Helper works fine as long as I keep my eye on it everytime it passes off a partially downloaded game as complete. However, the program takes literal hours to download a 1 gb game (Super Mario 3D World) and I go to look at the files, and there most of these app files that are all calculated in KiloBites or whatever KB are. Most of them 1 or 2 kb literally, some are over 10k. What are these files?
