1 Lesson 8 Revision Concepts of storage and directory structure Aim In this lesson you will learn: How to organise files and folder Naming files and folder Tejas: Moz, today we helped my mother at home to store the things she brought from the shop. Moz: What did your mother bring and where did you store them? Tejas: We put the sugar, coffee, grains, rice in the kitchen shelves. Jyoti: Aunty brought some story books. We put them in the story book shelf of Tejas s cupboard. Tejas: The bedsheets were placed in the bedroom cupboard. Moz: Good. So each item has been stored in a different place where they are used. Jyoti: Yes. Then we can find them easily. Tejas: It is just like I store my files in a folder named Tejas-files on the computer and Jyoti saves her files in the folder named Jyoti-files. So each one of us can find our files easily. Moz: What are the names of the files that you saved? Tejas: t-painting-house, t-story-fingers, t-song-flute Jyoti: j-painting-sun, j-story-tenaliraman, j-music-vocal Moz: Why is it important to choose an appropriate name for the files and folders? Tejas: It tells us what the file or folder contains. 82

2 Jyoti: Yesterday I was going home with my friends. Then we were reading the names of shops and schools. Imagine what would happen if our school is given the name food bazar and the shop that sells Moz: Yes. Name is very important. It gives an identity to a place, person, thing. Similarly giving appropriate name to a file or folder is very important. CONCEPTS Paintings, text that you create on a computer are saved in a file. We should choose a file name that tells us something about the contents of the file without opening it. Folders: The location where the file is stored is called the folder. Folders help us to organize related files together. Moz: Yes. Name is very important. It gives an identity to a place, person, thing. Similarly giving appropriate name to a file or folder is very important. CONCEPTS Folders in a computer help us by allowing us to keep related documents or files together. making it easy to locate important files quickly. Usha: A picture of Jyoti folder with the sub folders please. Moz: Very good. We know that if we keep all our photos on the desktop then it will look untidy. 83

3 Usha A snapshot of many photo files on the desktop. Tejas: Create folders for each student and move the photo into the folder. Moz: How do you move files into a folder? Tejas: By using drag and drop. Usha A snapshot of many folders on the desktop. Jyoti: It still looks cluttered! Moz: Create one folder for each class. Move the students folders into their class folder. Jyoti: That means we can move folders into other folders! Moz: Yes. The class folder is called the parent folder. The student folders are called the subfolders. 84

4 Usha A snapshot of class folders and subfolders on the desktop. CONCEPTS A folder that is created within another folder is called a sub-folder. The main folder is also called a parent folder. Using folders and sub-folders can help us keep our files neatly. Usha: A picture representing the above please. Jyoti: Can we have a school folder and in that the classes folders and then in each class the students folders? Moz: Yes. you can. 85

5 Tejas: Let us see how we can do this. Create a folder with the name of the school; this will contain information for students of that particular school. Within the school folder, create folders for each standard in that school, for example, std1, std2, and so on. These are sub-folders of the school folder. Similarly we can create further sub-folders within each standard for different sections, for example, std3a, std3b, and so on, and store files containing information about the students within these sub-folders. CONCEPTS This type of arrangement of folders is called a directory structure. A directory structure is usually represented by a tree diagram. school std1 std2 std3 std3a std3b Usha: Replace the above with screen shot and label the parent and subfolders. Moz: Under the folder Class-3A where will you store your files? Tejas: I will have to first find my folder tejas-files.then save the file in tejas-files folder. Jyoti: When I want to save my story then I must select my folder jyoti-files in the folder option. Moz: Correct. Then the file will be saved in your folder. 86

6 CONCEPTS Find the right folder to save the file. Select the folder. Save the file in the selected folder. Usha: A screen shot of choosing the folder in text editor please. Moz: If your friend Neeta wants to store her files, what does she do? Jyoti: Neeta is in class 3A. She can create one more sub folder under Class-3A folder called neeta-files. 87

7 Tejas: The postman keeps the letters of each building seperately. That way he finds the letters that he has to give us immediately. Jyoti: My mother does beautiful embroidery. Her embroidery box is neatly arranged. The coloured threads are all kept in one partition, the beads are in another partition, various sizes of needles are kept in a small box. She has some sequins in another partition. She says that, when things are arranged in their place, we can find them easily and we enjoy the work we do. Moz: Tejas and Jyoti, you have given very good examples. Now, give me a few examples of the above on the computer. Tejas: From Applications menu, when we choose games then we find all the games. Moz: Correct. Naming and organinizing files and folders is very important to find the information that you want easily. Moz: Meet you next year. Do all the projects that I have prepared for you in the next lesson. I would like to learn the game of chess from you next year. So be prepared! Chin Chinaki... Lesson Outcome After you have studied this lesson, you will be able to: Organise files and folders Choose a file name that tells us about the content and a folder name that helps us to organize and search for the files easily. 88

14 Book III Lesson 8 1. Pack your school bag according to the timetable: All the textbooks, class work and home work notebooks, rough book and school calender are mixed together in one pile. You have to pick up the books of a particular subject and put them together. Now pack your school bag according to the time table for the next day. 2. Tetravex: Tetravex is a simple puzzle where pieces must be positioned so that the same numbers are touching each other. The tiles are divided into four, you must position them so that only two numbers that are the same are next to each other. The game wil not let you position the tiles so that different numbers are next to each other. You position the pieces by dragging them from their current position to their new position. These moves are not permanent and can be readily reversed. The game is completed when you have positioned all the squares in the right positions. 3. Tux math: You mission is to save the penguins igloo from the falling comets. Stop a comet by typing the correct answer to the math problem and pressing the space bar or enter. If an igloo gets hits by a comet, it melts. But dont worry, the penguin is ok! Note the correct answer on the comet before it hits the igloo. 95

15 Book III Lesson 8 Group Activity Part A Write names of flowers, fruits, vegetables, sweets on chits of paper. Now mix them all and ask each student to pick one chit. Let students sitting in one row form one group. The teacher asks two students to find out names of all the sweets that are written on chits. Similarly, two students find names of flowers. Note that you will have to go to each group if you want to know the names of all the sweets. Part B Now, the teacher calls for each group one by one. First, fruits is called out. Notice that students from different groups who have the names of sweets will form the new group. Similarly, fruits, vegetables and sweets are divided into respective groups. Now you can go directly to a particular group and find out names of all sweets! Note that the new groups are formed because they share a common theme. Similarly, folders help us to keep related files together. Explore! 1. Find out how books are organised in your school library. 96

16 Teacher s Corner Book III Lesson 7 Students aleady know about files and folders. You can revise these concepts and explain the importance of using folders. Explain that files can be organised in different ways. Example: You are storing details of your family members in different files. You can have one folder that has all the photos, another folder that has voice recordings, another folder that has text on each of the family member. The other way of organising these files, is to have different folders for each family member. All the files related to this member photos, voice recording and text are put in this folder. Irrespective of which method you use to organise, there needs to be some order that has to be followed. This is for your convenience as you will be able to find the files easily later. To elaborate this point further, you can have an exercise, where you play a memory game with the students. Bring in a variety of things, jumble them up and spread it on the table. For example, you can get chalk, duster, salt and pepper shakers, peeler, knife, books, key, lock, bangle, bottle, tiffin, apple, banana, orange, etc. Now remove the cover for a minute and ask the students to look at these items. Cover it again and ask students to recall all the items they had seen. Take a count of how many items were correctly recalled and note it on the board. Now, segregate these items according to thier category, put all fruits on one desk, all kitchen items on the other desk and so on. Now divide the students into three/ four groups (students in one row in one group). Repeat the memory exericse again. Take a count of how many items were correctly recalled and note it on the board. This is likely to be higher than the first case. Explain that when the items are organised, it is more convenient to locate them. Explain the function of sub-folders. You can use the analogy that every page is a file, the notebook are sub-folders and the school bag the main (root/ parent) folder. For example, if you want to refer Lesson 3 from EVS, you will open the bag, pick up the EVS book and go to page of lesson 3. Ask questions such as: If they did not have notebook and only stacks of paper all piled together, how will they find the lesson 3 of EVS? Just as notebooks keep related pages together, the sub-folders keep related files together. Similarly, just as all the notebooks are put in your school bag, similarly all related sub-folders are kept in the main folder. Ask questions to encourage discussion and thinking amongst students. For example, what happens if your notebook goes in your friend s bag? Why do you need seprate notebooks for different subjects? Illustrate how sub-folders are created. To do this, create a folder called bag. Now create files that has names of lessons from Mathematics and English. Create subfolders with names Mathematics and English. Select a file with the name of a English lesson, drag and drop it the folder named English. Similarly place all the files in their respective sub-folders. Summarize the lesson and emphasize the importance of organising. 97
