This little AppleScript program tells the Finder to update its front-most window. It is very useful when you work with image files and programs that add custom icons to files. For instance, if you use GraphicConverter to rotate your pictures, their icons will be rotated as well, but the Finder is not going to see the change until you restart it. That's what Update Finder Front Window is for: it tells the finder to update its icons in the frontmost window.
