open notepad, go file -> save as -> call it zzz.lua, at the bottom, change it from "text file (.txt) to all file formats, then save it in Toribash/Data/scirpts
Make any type of file, it doesn't matter, you'll be renaming the extension .lua anyway. Just right click, go to new, click text document, then name it zzz.lua, If a window pops up asking if your sure you want to rename the extension click yes.
