The Tweaking with Vishal web site writes up a quick but useful registry hack that adds an "Open File Location" item to the context menu, just like Windows 7 or Vista has already.
Applying the tweak is simple enough—just download, extract and double-click on the registry hack file to apply the changes to the registry. Once you are done, you'll have a new item on the context menu that you can use to open up the folder that houses the file the shortcut is pointing to. It's a quick and useful trick for quickly accessing files buried deep in some installation directory.
