The left hand side of the Windows Explorer
screen shows different areas of your computer. In the previous
image, the left part of Windows Explorer starts with Desktop.
Next we have My Documents, My Computer, 3 ½ floppy, the C
drive, the CD Rom Drive, Control Panel and so on right down to
Recycle bin as the last option.
Click on the first option, Desktop, once with
your Left mouse button. This will show you all the shortcuts you
have on your Desktop, including the "My Documents"
shortcut we placed there earlier. But the list of shortcuts will
appear on the right hand side. And that is the main idea behind
the Windows Explorer - Clicking something on the left hand side
will bring up a list on the right hand side.
Click on the letter C in the left hand side of your Windows
Explorer. A list of all the files and folders on your hard drive
will appear on the right hand side. Like the one below, but with
different folder names on your computer.

When we create a new folder, it will appear on the right hand
side. But because we clicked the letter C on the left hand side,
the new folder will be created in the root folder of the C
drive.
The Root folder? What's that when it's at home? Well, the
rectangular yellow icons on the right hand side are all folders.
You can put one folder inside another. All of those folders on
the right hand side, and all the single files, are inside the C
Folder. The main folder on a hard drive is known as the Root
Folder. This is the symbolic notation for the Root Folder on the
C Drive
C:\
You can see that notation in the Windows Explorer address
bar. (If you can't see an address bar, on the menu bar across
the top that has File, Edit, View, Go, click the View option. On
the menu that drops down, move your mouse pointer to Toolbars.
From the sub menu that pops up, Click the words "Address
bar" once with your left mouse button.)
The Windows Explorer address bar looks like this:

Notice how the address bar says C:\. This is the
root folder of your C Drive, the folder in which all of your
other files and folders are placed. Watch what happens when the
folder on the right hand side called "Program Files"
is double clicked with the left hand mouse button. We get this:

The address bar now says C:\Program Files.
This means that there is a folder called Program Files, and this
folder is on the C Drive. On the right hand side is a list of
all the folders and files in the "Program Files"
folder.
Now that you know how the Windows Explorer
works, we'll now create our new folder.
