Sorry to say this but those XoloX programmers were just starting to program P2P and this was a quick and easy put together program. The easy way to do multi segment downloads is to create a large file and fill in the "blanks", it's harder to do it the way others are doing it.
But some of you people out there think this is the best client, it's like a cult and you are all crazy because this client was and still is very basic and any beginning programmer out of school could write this.
Have fun with your XoloX cult, humans are so silly.
