The in-game Settings window has a button that will open your Profile Directory in your operating system's default file browser. You will see the folders labeled "levels" and "doodads" which is where your custom created content will live.
***levels:** This is where your user-created .level files are saved to. You can also copy levels made by other players into this folder.
***doodads:** This is where your custom doodads go. You can copy doodads made by other players here and use them in your own levels.
***levelpacks:** This is where you can place custom [Level Packs](custom-levels/levelpacks.md). You can create your own or download packs created by other players and place them in this folder.
***screenshots:** the Giant Screenshot feature of the level editor will place its generated pictures here.
***settings.json:** holds your game settings and is unique to your installation of the game.
***savegame.json:** holds your progress through Story Mode level packs including high scores on the levels.
***license.key:** if you have [registered the game](register.md) this is a copy of your license key file.
Note: to back up your savegame.json you must also copy the settings.json file, or otherwise the game will not accept the savegame.json if the settings file doesn't "match" it.
