+# USE1.3 UNIX File System Tree
-# Background
 The UNIX file system is organized hierarchically according to the Filesystem Hierarchy Standard.
-UNIX follows the philosophy that everything is a file: Directories are indicated with a “/” separator and start from the root directory “/” and different devices are linked into this tree.

-Files or directories can be referred to either using absolute or relative file names.
-Typically, several elementary programs are installed that allows to access and manipulate files and directories.
