Solution

If you want to download a single file in multiple parts to improve performance then you will need to create an HttpWebRequest for each part and call its AddRange method to specify the range of bytes that you want that request to download. I've never done it myself so I have no example to provide but, if I wanted to do it, the first thing I'd do is read the MSDN documentation for the HttpWebRequest.AddRange method and then search the web for that same method.
