5.1 The File System
5.1.1 Sample user directory structure
The Figure shows a sample UNIX file system structure for a user. This is the Class File Tree Structure which you will refer to throughout this chapter and again later in the course. This structure should exist in each student's home directory. Note that there are directories, subdirectories and files in the structure. Directories and subdirectories have a folder icon and files have a document icon. The exercises in this and subsequent chapters use this directory structure.

The structure and names of directories within a user's home directory can vary considerably depending on the user and their needs. For instance, a user could have major directories named Projects, WPDocs, Finances and Hobbies under their home directory. The names of the directories are determined by their purpose and what they contain.
