A file manager is like a teacher's desk where you can see all the papers and books that the teacher uses to teach you. Just like how a teacher organizes their desk to find the right book or paper, a file manager helps you organize and find your computer files easily.
When you have lots of files on your computer, like pictures, music, and documents, it can be hard to find them all. But with a file manager, you can see all those files in one place, and move them around to different folders to keep them organized.
It's like having a toy box with lots of toys in it. If you don't keep them organized, you might lose your favorite toy or forget where you put it. But if you put all the toys in specific spots within the toy box, you can always find what you're looking for.
With a file manager, you can see all the folders and files on your computer, open them to see what's inside, and move them around to different spots. This helps you to find what you're looking for quickly, just like how a toy box helps you find your favorite toy.
