How to Open African Random Map Files?

I try to open new African random maps .xs and .xml files with Notepad and Notepad++, but the only thing I can see are those weird codification symbols. Is there a way to see the original code?

I want to know how water trade routes are placed…

This is unfortunately intentional, to prevent modders from copying the maps and making them available to everyone for free, while they should be available only to those who own the African DLC.

You mean those who have DLC can see the orignal code?

No, the original code is encrypted as you see, specifically to prevent anyone from copying it or looking at it.

I also want to know how to view it, can anyone help me?

You cannot view the African map scripts. Like I said, they are intentionally made unreadable.
