The File System Hierarchy is a structured way of organizing files and directories on a computer. It allows users to navigate and manage data efficiently. At the top of this hierarchy is the root directory, often represented by a forward slash (/), from which all other directories branch out. Common directories include home, etc, and usr, each serving specific purposes. Within each directory, files and subdirectories can be created, forming a tree-like structure. This organization helps users locate files quickly and maintain order. Understanding the file system hierarchy is essential for effective file management and system navigation.
