Change route/folder precedence in IIS/ASP.NET MVC3

Question

If i have a folder named xxx and a route like this:

routes.MapRoute(
    "TestRoute",
    "xxx/{action}",
    new { controller ="xxx", action="Index" }
);

By default, when i request /xxx, IIS will try to return a directory listing, but I want my route to have precedence over folders/files on requests.

How do i do this?

Here's a post that describes your issue and has a solution: http://forums.asp.net/t/1251156.aspx/1

Here's the meat of the answer on the link I provided:

By default, DirectoryListingModule take precedence over UrlMappingsModule. Fortunately, it is possible to change the order of UrlMappingsModule and DirectoryListingModule.

Goes to IIS7 Manager -> Modules, in the right pane, click View Ordered List, you can then use Move Down, Move Up to change the order of modules.
