Because it’s a god-send: This file can be added to any other mod or just the core game itself, and will allow you to zoom further out.
Also, if you’re unaware, you can edit C:\Users\<username>\Documents\Command and Conquer Generals Zero Hour Data\options.ini (may be other places in other versions of Windows) to increase the resolution above what is available from the in-game menus. In my case, I change the Resolution line to
Resolution = 1920 1080
Cheers!
