Hello Dark Ownage, seeing as you never received a proper greeting to AoMH, I will take the time to do that now... Welcome to AoMH, we hope you enjoy your stay.
Now, to answer your question; there are two places your scenarios are stored. The first place is:
My Documents/My Games/Age of Mythology/Scenario
The second is:
My Computer/C:/Program Files/Microsoft Games/Age of Mythology/ScenarioNow, these are the default paths, you may have installed AoM in a different location. If that is the case, go to that location instead.
Now, if you go to the first place I mentioned, and all you see in a ".bar" file, that means that you need to extract the scenarios from a compressed file called a "BAR". To do this, you must download a program called AoMEDAlso, in the future, please use the question thread for any more questions, thanks.
oh you can wait for what I can give
you know what I am so you know how I live
try to look proud but you’re not in the slightest
its happening now and it’s always been like this.
