            3.4. WHAT IS A FILE?

            Any data in the computer is stored in the form of a file. That is why a file is said to be a collection of logically related
            data. Every file has its own unique name which is made up of two parts: file name (A filename can consist of letters,
            numbers, spaces, and characters) and extension (that identifies the file type). They both are separated by period
            (. ). For example,
               Mynotes.docx      →    is a MS Word file.
               Myproject.pptx    →    is a MS PowerPoint file.
               Myfriendslist.xlsx  →   is a MS Spreadsheet.
               Essay.odt         →    is an OpenOffice document.
               Photo.jpg         →    is an image file.

            3.5. WHAT IS A FOLDER?

            Folder is a collection of related files and subfolders. A sub-folder may contain one or more files and subfolders
            within. Folders do not occupy any disk space. They point to specific file locations within the file system of the
            computer. There is no limit on the number of folders or subfolders that can be created in Windows. The main
            advantage of creating folders and subfolders is that it helps in organising the data found in the system in a proper
            hierarchical manner.


            3.6. CREATING AND MANAGING FILES AND FOLDERS

            Since folders and  subfolders are organized  following a proper  hierarchical file system of any  storage  device,
            sometimes they are also called directories or subdirectories .The first directory in the hierarchical system is called
            root directory and is represented as C:\ or D:\.
            The folders and files are created within the root directory. To access any file, folder or subfolder we refer to a File
            Path which allows quick access to a file.
