When not working on computer, you use paper sheets to write important information. You would, oQviously, like to keep these important write ups in a well organized way and with safety. And, to be doubly sure about the safety of your sheets, you may prefer to bind them together in a book form.



In computer terminology, 'file' is like a paper sheet and a 'folder' is akin to a book. Just as a book contains pages, a computer folder consists of files. Fig.WE-18 illustrates the relationship between files and folders. We can, therefore, say that in Windows, a Book is referred to as Folder and a Paper Sheet as File.
