Deluxe Ski Jump Forum

Hello I have a question, I wanted to add some custom hills but I couldn't find the custom hills folder.
I searched for an tutorial and I saw that the people online also had folders like online ,team cup etc.
I also didn't have those.
Pls help

The folder is located in my document, the deluxe ski jump 4 folder, and in it is the Custom Hills folder and it loads the hills into that folder.
