I heard awhile ago that you can put all your custom content for mapping in a separate folder, you can keep better track of it. Today, I decided to do that. All of my custom content is in a folder named "tf_custom" in "Steam\steamapps\common\Team Fortress 2", next to the "tf" folder. Now, how can I use this folder? I assume you have to add it to "gameinfo.txt", but where does it go?
