AIM
In this lesson you will learn:
How to organise files and folder
Naming files and folder
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.
Kaumudi: A picture of Tejas and Jyoti helping Tejas's mother to store the items that she brought from the shop.
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?
Kaumudi: Mother with the items on the table. And pictures of Tejas and Jyoti putting them in different places against each one as they say where they have put the particular item.
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 on the computer and Jyoti saves her files in the folder named Jyoti. So each one of us can find our files easily.
Concept: Files are created on a computer and saved in a file for future use. We choose a file name that tells us something about the contents of the file without our opening it.
Folders: The location where the file is stored is called the folder. Folders help us to organize related files together.
Moz: Do you store all the files in one folder?
Jyoti: No. I store music files in one folder, paintings in another and my stories in another folder.
Concept: 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 subfolders please.
Moz: Very good. Now suppose each student in the class wants to save the files in their own folder on the computer. Then the desktop will be full of folders. So what can we do?
Jyoti: Create a folder with the class name. The folders of the class can be stored in this folder.
concept: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 organise data very efficiently.
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.
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.
Concept:This type of arrangement of folders is called a directory structure. A directory structure is usually represented by a tree diagram.
Usha: Please add a few children folders for std3A and std3B in the above directory tree.
Jyoti: When I want to save my story then I must select my folder jyoti in the folder option.
Moz: Correct. Then the file will be saved in your folder.
Usha: A screen shot of choosing the folder in text editor please.
Moz: 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: The first folder that you start with is called the root folder.
Jyoti: Then Applications is the root folder.
Tejas: And in the directory structure school is the root folder.
Moz: Correct. Naming and organinizing files and folders is very important to find the information that you want easily. When you are going home observe the names of places. Imagine what would happen if your school is given the name food bazar and the shop that sells vegetables is called the Zephyr school!!
Kaumudi a picture of Jyoti and Tejas imagining the above and laughing.
Moz: Meet you next year. Do all the projects that I have prepared for you in the next lesson. Chin Chinaki.
