This is a short explanation of the Linux file system Hierarchy. In a Linux system, all files are stored on file systems. A file-system hierarchy is the organization of these files into a single inverted tree of directories. The tree of directories is said to be inverted since its root at the top of the hierarchy, and the branches of directories and sub-directories stretch below the root.
