Managing Folders In Documents Library

I am not able to find the process to delete a folder from my Documents library. The F1 function says the following, but I cannot find the 'library pane', Includes, nor Locations. When you no longer need to monitor a folder in a library, you can remove it. When you remove a folder from a library, the folder and its contents are not deleted from their original location. In the taskbar, click the Windows Explorer button. In the navigation pane (the left pane), click the library that you want to remove folders from. In the library pane (above the file list), next to Includes, click Locations. In the dialog box that appears, click the folder you want to remove, click Remove, and then click Ok.
