How it works, Lets say you are downlaoding A 22mb File. through the Enable Xp ED2k network.. Instead of relying on just 1 source, Enable Xp breaks it into chunks, approx 9mb chunks, and it will download these chunks from more than one source. So if 1 part gets corrupt or the user go offline, no worries, you haven't lost the entire download. Worst case scenario 9mb of it, and chances are it's already downloaded from somewhere else.
