Everyone is close, but not quite right.

using (SPSite site = new SPSite("http://server/site"))
{
  SPWeb web = site.RootWeb; // See disposal guidance http://blogs.msdn.com/b/rogerla/archive/2008/10/04/updated-spsite-rootweb-dispose-guidance.aspx

  SPQuery query = new SPQuery();
  query.Query = @"
          
            
              
              0x0120
            
          ";
  query.ViewAttributes = "Scope='RecursiveAll'";
  SPList list = web.Lists[listId];
  SPListItemCollection items = list.GetItems(query);
  // Do stuff with your folders
}

First of all, using this FieldRef is wrong:

Folder

because the folder content type can be inherited. Therefore, you need to compare against the content type ID, like this:

  
    
    0x0120
  

And then, set the view attribute Scope to RecursiveAll

...

That should return any item whose content type inherits from Folder (0x0120)
