Try like this:

[HttpPost]
public ActionResult Upload(IEnumerable files)
{
    if (files != null && files.Count() > 0)
    {
        foreach (var uploadedFile in files)
        {
            if (uploadedFile.ContentType != "image/vnd.dwg") 
            {
                return RedirectToAction("List");
            }

            var appData = Server.MapPath("~/app_data");
            var filename = Path.Combine(appData, Path.GetFileName(uploadedFile.FileName));
            uploadedFile.SaveAs(filename);                    
        }
    }

    return RedirectToAction("Success");
}

and modify the markup so that the file inputs are named files:

...// many inputs type file
