Hi Lee, the short answer to your question is no - they aren't supposed to be there. However, they won't cause any problems (to my knowledge) with FS9 on their own. The only issue you'll encounter is that any aircraft which are installed to that second aircraft folder won't be available to fly in FS9, however this can be easily fixed by simply moving that aircraft's folder into the main FS9 aircraft folder. I don't have an extra gauges folder in my main aircraft directory, but if there are files in it then I would keep it there for safe measure
