So, I was going to mod a game, but found out that in order to do what I want to do I'll have to edit a few lines of text in a number of .txt files located in a single folder. We're talking about hundreds of files here so manually doing this would be pretty tedious. I'd like to know if anyone here can recommend a program that can do this. Basically it needs to have an input string where you can enter a value, and if the file has that value it changes it to something else. Any advice?
