Where is my minecraft jar file

I have a problem.I can not find my jar folder for minecraft.I have 1.7.4.So does anyone know where the jar file is?


Solution 1:

Open Start menu, if in windows 7 type in %appdata% and press enter, if on widndows xp open start, click run and type in %appdata% and press enter. When i %appdata% folder, open .minecraft folder and then go to bin or versions. If in versions folder just open the folder that has the name of the minecraft version that you are looking for.
