I have the following on my page:

This component is sending an application/octet-stream instead of multipart/form-data which is what the default model binder can work with. So you cannot expect Request.Files to have any value with such a request.

You will need to manually read the request stream:

public ActionResult Upload(string qqfile)
{
    var stream = Request.InputStream;
    var buffer = new byte[stream.Length];
    stream.Read(buffer, 0, buffer.Length);

    var path = Server.MapPath("~/App_Data");
    var file = Path.Combine(path, qqfile);
    File.WriteAllBytes(file, buffer);

    // TODO: Return whatever the upload control expects as response
}
