Find Your Way Back to the GAC

Have you ever wondered where your assemblies go when you put them into the GAC ?  If you’ve ever tried to find the file location of one of your GAC’d assemblies, you probably know that there is no way to look it up from the <WINDOWS>\assembly directory. 

There’s actually a hidden folder that isn’t seen even if you “show hidden folders” where Windows stores GAC’d assemblies.  To get to it, you’ll need to create a shortcut to 


When you try to create a shortcut through the normal means, the shortcut creation wizard won’t allow you to use this as a target.  The work-around is to create a shortcut that points to another folder and then paste the above into the Target under the properties for the shortcut.

Double-click your new shortcut and Voila!  The file locations for every version of every assembly in the GAC.
