If something goes wrong, you’ll want a clean copy to start over with. When you find it, make a copy of ‘minecraft.jar’, and stash it somewhere. Open the folder titled ‘bin’, and look for the file ‘minecraft.jar’–this is where the magic happens. The folder ‘.minecraft’ will be at the top. Click the Start button, and type ” %appdata% ” into the search window (without quotation marks but with one space before and another after the typed string) to get to Windows’ application data folder.
