Wii homebrew

Ned help withthe wii gecko os code manager. i have downloaded the code manager and gecko os. the problem is that i dont knoiw where to putthe text files for the code. When i click on the "codde manager" icon wen i open the zzipped folder it says "open with what". where do i put the codes?

u put all the text code into a text file(.txt extension) with the name of the game by region(R8PE01) and it should be like this final b4 u put it into code manager (R8PE01.txt) with the codes inside. then u open code manager then file open find taht r8pe01.txt and select it. afterwards ull see a list of codes, tick w.e u want then go to file export then select a place to store it. after you store it, open ur sd card and make sure u have a folder name codes on the root of the sd card. put that file(i think its with a gct extension) into the codes. then run with v.3 bakuplauncher or gecko os and make sure ocarina cheats r on
