Being able to see the full path (i.e. D:CollectionVideosMusicVideosclip.avi) rather than just the directory in which a file is located (i.e. MusicVideosclip.avi) helps a lot when one has opened many folders and needs to frequently switch between them. And if you happen to have folders with the same name located on different drives or in different subfolders, than enabling this option is a must to avoid confusion.

To enable this option, go to Folder Options in Control Panel and open the View tab. Alternatively, you can open the same tab if in a Windows Explorer window you select the Tools menu. When the View tab is open (as shown in this screenshot – screenshot), put a tick in the Display the Full Path in the Address Bar check box and click Apply. Now you should be able to see the whole path to a file or folder.
