To open it you need software capable of doing it (most archivers can do it), to run it, you need software capable of doing it (Oracle JAVA).

JAR files are containers for JAVA executable code. By default Windows does not know how to use it untill you install software capable of managing them.

I could immagine situation that JAVA refuses to RUN it (remmember that archivers can open it), cuz of outdated JAVA or wrong JAVA (there is JAVA SE intalled with some browsers, not good for everything else), problems with multiple JAVA intalations (generaly you need only one), and finaly damaged .jar file, fake .jar file and such. Also there is a situation where it has actualy run, but ended with a crash, closed everything before you even had a chance to see it. try running it with batch, that has pause command at the end to see window output.

eg

c:\Program Files\Java\bin\java.exe -xmx1G -Xms1G -jar MinecraftForge.jar
pause

Also note that sometimes you need to encapsulate certain pats of commands with quotes, cuz operating system does not recognize blank spaces in names as part of the names giving resulting batch file this kinda looks

eg
"c:\Program Files\Java\bin\java.exe" -Xmx1G -Xms1G -jar "My custom named file.jar"
pause

Also note i gave you examples, you should not just copy-paste it, might be different folder structure on your computer.

You make one, its a text file, that has .bat extension (on operating systems that are not made by microsoft, it is called shell script and does not require to have extension, still it is simple text file) . Can be done with any text editor. You could google to it, its not something for this forum to resolve.
Double clicking on it will execute console commands in sequence.

Im confused on how to open the .jar file.... could u give me steps or is that not possible??

Install WinRAR archiver
Run it.
Select "OPEN" from the menu
Navigate to .JAR location.
Select JAR file
Click "OPEN"

It will show you content of JAR file

You could use 7-ZIP archiver instead, its free

Forge installer for 1.6.2 is downloaded from here:

http://files.minecraftforge.net/

File name of that installer is not even close to anything you mentioned previously.

Now let me quote myself a bit:
