https://youtu.be/m3kC85nEFQAI went the extra mile and added folder and file icons next to the file/folder names as well.

I finally coded a file open dialog that :
1. Works with limited bugs, lol
2. Has the ability to change folders.
I still have to tweak a few things but I'm happy with what I've done so far. I'm using classes instead of objects so its good in that way also to learn something new.
My next task is to do a dialog box for saving a file that can change folders instead of the simple pop-up input line box I coded.
