minecraft.jar is just the file that has the information used to run the game, it is not the actual game. You must open Minecraft with "minecraft.exe"
If you do want to open minecraft.jar though for any reason, such as installing mods, you can do so by downloading a program such as WinRAR, and using it to open the file.
The easiest way to locate minecraft.jar is to open your "run" window and enter the following: %APPDATA%\.minecraft\bin This will open a window for the folder that minecraft.jar is in.
open minecraft click mods and texture packs then click open texture pack folder then at the top of the document window click .minecraft and then double click the bin folder and it should be in there
