Amnesia Custom Stories Help

I'm not sure how many of you have tried the Amnesia custom stories out there, but I seem to have something of a problem. I can't find out where I'm supposed to put the custom file after it's been extracted.

I've looked up tutorials, and they all say to played it in the Steam/steamapps/common/amnesia etc etc. Thing is, I did not download the game from Steam. I bought it via Direct to Drive. Here are the files I see when I open the main Amnesia folder:







Going under the name of my save file I see "user settings" and "user keys", and a whole bunch of save files. I see nothing that indicates where to save the custom file.

If someone could help me, I'd be most thankful ^^
