Tin học 3- Bài 21: Tạo, đổi tên và xóa thư mục

Hello everyone, today I will teach you the 21st lesson of creating, changing names and deleting chapters. Before learning the lesson, I will let you observe the following chapters. I have chapters 3A1, 2A4, 2A5. In this chapter, I have chapters Hồng, Kiên, Lan. In chapter Lan, I have chapters Động vật, Hoa, and Bao Toi. In this chapter, I will teach you how to create these chapters. First, we will go to the small section to create a chapter. To create a chapter, we will go to a PC. We will go to the D and E of the computer. You will enter the phone number. Then you will look at the New Order button. There is a yellow button. Click it. When you click it, a folder will appear here. The word is in blue. You will use the backcat or delete key to delete this word. We will name our chapter. For example, I will name it 3A3x25.26. That is, class A3, class 5, class 5, class 5, class 6. Then we can delete it. Or you press the Enter button. We have created a chapter. After creating, we will press the delete key to open this chapter. You can see that we are observing this guide. If you observe this guide, you will see that there is the word 3A3x25.26 here. That is, we are in this chapter. Next, we will create the sub-chapters of this chapter. The names of the members in the group. Similarly, we will click on the New Order button. Please note that we are still in the Home tab. We will name it. For example, we will name it Hong. The teacher does not hide it. Then press the Enter button. The next chapter is Hanh. Press the Enter button. Next, the teacher will guide you to create sub-chapters of Hong. We will do the following. You will open the sub-chapter Hong by clicking on it. At this time, we see that there is a word Hong above this guide. That is, we are in this chapter. And we will click on the New Order button. Similarly, we will create sub-chapters such as the chapter of Photos. To create another sub-chapter is the chapter of Exercise. Next, if you want to create sub-chapters of Con, sub-chapters of Hanh. We will have to go out. You will click on this name. We have to go out. Or the second way is to click directly on the 332526 layer. We will also go out. And you will do the same. You create sub-chapters of Con, sub-chapters of Hanh. So I just taught you how to create sub-chapters. Please note that in the same sub-chapter, for example, in the same sub-chapter 332526, we are not allowed to create sub-chapters with the same name. If the names are the same, the computer will tell us that we are not allowed to create. Please note that. Now we will move on to the second step, which is to change the name of the sub-chapter. You go through here. In this part, the word Hong and the word Hanh are not hidden. Now we will change the name back to the word Hong is hidden as follows. To change the name of the sub-chapter, we will click on it. Click once on the left button. And we will click on the word William. There is a symbol like this. After that, our word has changed to green. You can delete it or write it directly. You don't have to delete it. You change it back to the word Hong and press Enter. Similarly, we do the same with the word Hanh. Oh, there is another way. There is another way that we don't necessarily have to click on the word William. That is, we click once on the word Hanh and we take a break for a while. And we click on the word Hanh again. We just have to click on the word Hanh. Our word Hanh has also changed to green. And we don't necessarily have to click on the word William. We have two ways. Click twice, but we click the wrong way. Not the right way. I do it again. Click once, take a break. Then we click once again. Then we can change the name. Click Enter. Similarly, we go inside. We edit the sub-chapter and the word Hanh in Vietnamese. Next, I will show you how to delete sub-chapters. In the process of creating sub-chapters or in the process of using computers, there are some sub-chapters that we create but we don't use them. Then we need to clean up so that our computer doesn't get damaged. We will do it like this. I will go outside of the computer. For example, in the computer of the teacher, there will be some sub-chapters. Before deleting the sub-chapter, we need to check the sub-chapter carefully. See if there are any errors in the sub-chapter. For example, in my computer, there are two sub-chapters. That is the sub-chapter New Photo and New Photo 2. Now I will open it to check. In this sub-chapter, I see that the sub-chapter is empty. There is nothing. I will go outside. And I will do it like this. To delete the sub-chapter, first we will select the sub-chapter. And we will select this x symbol. Click Delete and click here to delete it. Next is New Photo 2. I will show you a second way to delete it. You can still click on it. But we will look at our computer. There is a Delete key. It also has the word Delete like this. There is also the word Delete like this on the computer. Then we will click on the Delete key to delete it. So we are done. So we should delete the sub-chapters that we do not use. Or the sub-chapters that we create. You delete it to make our computer look cleaner. I just introduced you to 3 operations. Create, change the name and delete the sub-chapter. You need to do it over and over again. To be able to memorize and master these operations.
