i found some Arkham world files in my pc

So i don't know what's the deal with Arkham world, never knew anything about it before yesterday

I was doing some digging in my files when i stumbled upon some Arkham games files

There was an Arkham knight, city and origins folder

And then there was an Arkham world folder, i opened it to check it out but sadly there wasn't anything actually readable/useful in it

What's up with that?
