========================================================================

• Windows uses icons to graphically represent items, such as programs and folders. 
• This is part of Windows GUI, or graphical user interface. , an interface that helps the user to interact with the computer easily as here the user doesn't need to memorize the commands.
• Icons appear everywhere throughout Windows, and are really just pictures that depict the type of items they represent.
• The Windows desktop contains a range of desktop icons. Many of these icons are known as shortcuts or links to frequently-used programs, folders and files. 
• You can save a lot of time and reduce the number of mouse clicks in a day by creating desktop shortcuts for frequently-used programs.
• Shortcuts to programs, files and folders can be added easily to the desktop, as well as arranged, moved and removed. You should also clean up your desktop from time to time when it becomes too cluttered.

Various Icons -  What They Represent

Programs

• The icons containing an arrow to the left represent shortcuts to the program.
• So, if you were to delete the shortcut, you wouldn’t be deleting the actual program, only the desktop link to it.
• 
  
• Double-clicking on the relevant icon will launch that program. For example, if you double-click on the icons , you will launch the application.

Files

• Icons that show a page represent a file. 
• When we double-click on the icon, the file will open in the program that it was created in. 
• However, as no arrow appears, it is not a shortcut, but indicates that this file was actually saved to the desktop. 
• Therefore, if this desktop icon is deleted, so is the actual file.

Folders and drives

• Icons that show a folder represent a folder or shortcut to a folder. 
• When you double -click on a folder icon, the Windows Explorer window will open and we will see the contents of that folder. 
• Similarly, icons that show a hard disk will display the contents of that drive in Windows Explorer when you double-click on it.

Recycle Bin

• The desktop icon for the Recycle Bin is shown as a waste paper basket with the recycle symbol on it. 
• Double-clicking on this icon will open the Recycle Bin window, allowing you to permanently delete or restore files as necessary.
• If  we select a file/ folder and press SHIFT+DELETE, the selected item will not be sent to the recycle bin and will be permanently deleted.
