Autoexec.cfg it’s a file, checked by Enemy Territory every time you start the game. When autoexec.cfg is found and automatically loaded, your game will apply whatever scripts, binds, settings you have in it.
If it doesn’t exist, you can create one. Basically it is a text file, so you can simply create or edit in any text editor. Just open notepad for example, add your settings or binds and save it as text file with .cfg extension. When you are done, copy your file in your installed game folder: “C:\Program Files\Enemy Territory\etmain\autoexec.cfg”
You can also manually load this file, even while you playing, by typing the following in the console:
