I don't have Core files in my Wesnoth folder?

[Hojie_Kadenth]

If I go to my Wesnoth folder, then data, I only have 1 folder I can open and that is "Add on." I search for a core or campaign file in my computer and it can't find anything outside of the add-on folder. How do I get the core folders? I assumed I would have them, as I did previous times that I had this game. Thanks.

If you run Wesnoth and click the "i" button in the bottom left corner, it will display a list of folders. The one you're looking for is the first one, the "Game data" folder. Clicking the folder icon will open the folder using your operating system's file manager. Look inside the "data" subfolder to find campaigns, core files, etc.
