Roots

In the process of dividing up the drive, a few new naming conventions had to be introduced. This structure system calls the first point the root. The top-most directory in each drive is called the root, and you’ll usually see it referred to as C:\ or D:\.

An analogy that may help you visualize what is going on would be that of a tree that is upside down. Like a tree trunk, the root is the base. Unlike a tree, leaving the root going to the branch system is referred to as going down.(A tree trunk goes up the branches)

Each branch is known as a sub directory, because it is a sub off the root directory. When windows and its graphical interface became popular, the sub directory started to be known as a folder, because the icon to display the structure looks like a file folder – hopefully providing an easy-to-remember way for users to think of where they’ve stored their data.

Like a tree, branches can have branches, and there can be more then one1st level branch from the root. How the structure is created is up to the user.

Making a new branch on any level is done with the MD command, short for Make Directory.

To move to a sub directory, use the Change Directory command, which is CD.

To remove an empty folder use the RD (Remove Directory) command.
