Mac OS X 10.5 Leopard added an optional Path bar at the bottom of folder windows to display the path of any selected file or folder. Double-clicking a folder in the path opens that folder. Drag (or Option-drag) a file to move or copy it to one of the folders in the path. This feature first appeared as the Address bar in Windows Vista, which began appearing nearly a year before Leopard shipped. The Windows version has a bit more functionality, in that you can click an arrow next to a folder in a path to get to anything inside it.
