File extensions are simply part of the file name. Your operating system will often use the extension part of the file name (after the dot) to determine which program to open the file with. You could make a simple batch script by opening a .txt file, adding the scripting stuff into it and saving it as a .bat file. Your operating system will then treat it as a script you can run rather than opening it directly in a text editor.
