Thanks,
FileExists worked fine for my purpose and I quickly made my own function to get the parent directory.

Now a completely different kind of question. How do I register when my window loses focus? I've noticed that the window stops rendering and that's fine. However I'm playing music through the Bass library and music will continue to play when the app loses focus. So I need to know when the app loses and gains focus so I can manually pause and play music.

If it makes a difference I'm inheriting from TSvPrototypeGame.
