How to navigate in Windows
Vista includes an enhancement to the Windows Explorer navigation bar. The bar now shows not just the folder you are currently navigating but also the folders that you had to open to get there, meaning that there’s a visual trail of ‘breadcrumbs’. Each folder in the trail has an arrow next to it — click it and Explorer displays the other folders it holds, making it easier to retrace your steps.
