A file system is like a big library where we keep all our files like books. A hierarchical file system is like a big tree with many branches. Imagine a tree starting from the top with branches spreading out from it, just like the box in our computer where we can store our information.
The first branch is called the root directory, and it's like the trunk of the tree. Just like a tree has many branches starting from the root, the root directory also has many other folders branching out from it.
Each folder is like a branch of the tree, and it has files and subfolders inside. We can name each folder whatever we want, just like we can name different trees.
Just like we can climb a tree and reach a branch and then climb further up to reach another branch, we can also access subfolders inside a folder within the file system.
So, a hierarchical file system is like a big tree, where we can organize our files and folders in a systematic way. We can access each folder and its contents by following the branches of the tree or the directory path. This makes it easy to find and manage our files.
