[Other Question] Folder Question

I was wondering if I could set subfolders in graphics folders to sort trainer sprites or whatever. It's kind of overwhelming for me personally but if it makes it so RPGMaker can't read the sprites than I can make myself deal with it. I was just wondering if anyone knows if I can make subfolders or if I have to edit code or what's up with that.

You would have to edit the code, yes. Certainly possible, but probably more hassle than it's worth, to be honest.
