itch.io

I'll be honest I have read over the instructions over and over and I still am not figuring it out as I have gotten sims through Electronic Arts and no matter how much I look at the data folder I'm not finding where the worlds are located. I am more of a visual learner so it's difficult by reading it. So, if anyone can explain it to me step by step (as if I am a child) that would be awesome! please and thank you.
