A "simple" download question

[Windhund42]

Greetings all,
                         I have a very simple technical question I'm sure will not be difficult to answer.  I downloaded a scenario and subscribed to Winzip to be able to open it of course.  For some reason, I see the zipped scenario in my Downloads file but I can't make it work.  This is what I do:
 
                           Find Matrix Games folder
                           Find JTCS
                           Find East Front (in this case)
                           unzip scenario into EF
                           

The scenario does appear as a separate file in the EF folder which I think is odd because none of the dozens of other scenarios I have in my game have their own folder.  It used to be so simple using Winzip to download a scenario or it must be me not keeping up with all of its new "features"

I imagine the solution is simple but as I get older, I'm getting "simpler" by the day lol.
