The Folder Bar, which displays the folders of your computer in an expandable and collapsible manner, can be very handy when browsing through the files and folders on your computer. While this feature is set to appear, by default, in Windows Explorer, it is now shown when viewing My Documents of My Computer. To make the Folder Bar viewable (from within My Documents or My computer), click on View > Explorer Bar > Folders. The Folder Bar should now appear in a panel along the left side of the window.
