Off topic - Downloading Scenarios

[Crossroads]

Those are propably the files you should save to West Front or East Front folder.

Let me walk you through this with an example.

1) Open the scenario database for Campaign Series West Front scenarios
2) Download the zip file for the first game in the listing, "The Monster"
3) As a result, you get a file called "Oberhoffen.zip"
4) This zip file includes four files Oberhoffen.scn, Oberhoffen.map, Oberhoffen.bmp, Oberhoffen.org
5) Place these four files to West Front folder, under John Tiller Campaign Seris folder.
6) You should now have "The Monster" available when you start West Front

I hope this helps...

EDIT: I reread your original post. If what you are asking is how to download every and each scenario file in one go, I am afraid it is not possible. You need to download them one scenario at a time...
