Need to perform basic file operations In any school (or office), each teacher has a separate cabinet, as shown in Figure 3.32 where they keep the files of different students/classes on separate shelves. Similarly, information on a computer is stored in Figure 3.32: File Cabinet A. Multiple choice questions 1. Which of the following functions are performed using a mouse.

It is easier to manage the electronic files as they can be simply copied, moved, renamed or even deleted. Files and folders All information stored in a computer is kept in files. Different types of files store different types of information. Each file is given a file name and has a file name extension that identifies the file type. (The file name and file name extension are separated by a period or a ‘dot’.) For example, a document (e.g., with the name Neha) created using Notepad (a type of computer application to create simple text files) will have the extension .txt. There are other types like .doc, .xls, etc. An image file usually has an extension .jpg, while a sound file usually has .mp3. A folder is a location where a group of files can be stored. Creating a file (using a text editor in Ubuntu) When a student, Neha, joins a class, the teacher creates a file on the computer to store Neha’s information, such as name, address, phone number, etc. Let us create a new file using a text editor in Ubuntu. • To open a text editor, type ‘editor’ in the search dialog box. Then double-click the text editor option as shown in Figure 3.33 and 3.34. This will open a blank document. In Windows, you can open Notepad and type in the text.

The module will include videos and e-content for the above topics as well as detailed instructions for some activities below. Initial thinking activity After watching the initial video in the e-learning lesson for this topic why do you think it’s important to know how files are stored in a computer? Activity 1 Create a file Materials required Pen/pencil, notebook, computer Procedure • Form groups, depending on the number of computers available. Each member of the group creates a file. Others can watch and give feedback on what was done correctly and what can be improved. • Open a text editor in Ubuntu or Notepad in Windows. • Type details, such as name, class, address, parent’s name, etc., for a student • Save the file on the desktop. Each student studies the shortcut given below: CTRL+z undo CTRL+y redo CTRL+a select all CTRL+x cut CTRL+c copy CTRL+v paste CTRL+p print CTRL+s save The first group asks the other groups a questions (e.g., what does CRTL+Z do? or what is the shortcut for Copy). Figure 3.35: Saving a File • Here you can add text, such as ‘Neha Tiwari, Shakti Nagar, New Delhi. M: 7856453451’ • To save the file click Save. In the Save As dialog box, browse to the Desktop folder, type the name as ‘Neha’ and click Save as shown in Figure 3.35.
