Help with custom stories

[DeltaDuck666]

Try extracting to the desktop, then moving them to the custom_stories folder.

How does one extract a file? Sorry, I'm Dutch so I don't know exactly what it is. By extract, do you mean move it out of the map where it is and onto the desktop?

I have managed to get one custom story working, A lot of stories, but I've also tried two others: Monsters and InAHeartbeat. The working one was already a map with other maps like: entities, maps, that kind of stuff, but the two that don't work appeared as RaR. files with an Internet Explorer icon next to it, I don't know what to do with them. I've tried opening them, because it seemed like the only thing to do, but it doesn't work for some reason.
