The root directory of a hard drive is the top most directory in a hard drive. Each hard drive has its own root directory. All other directories or folders on the hard drive lie below the root directory. In the Windows and Unix operating systems, it is easy to display the files in the root directory of a hard drive. Even for those who prefer to use the command line, the process is still very simple. In a Linux or Unix system with a GUI, you can do something very similar to the Windows example above using the file browsing program that is available on your Linux or Unix system. The file browsing program you use varies from operating system to operating system. In Unix and Linux, type “cd " to change your command line to the root directory for the boot drive. To get the root directories other hard drives, run the “df” command to get a listing of mounted filesystems and use the “cd” command to get to them. For example, if another drive is mounted as /export, the “cd” command you run is “cd /export.” Writer Bio
