→Unix / Linux File Management Concepts
Files are organized in directories. Directories may contain sub-directories.
In Unix / Linux (as opposed to MS Windows), there are no drive letters (such as C:, or D:). All files and directories appear under a single ancestor directory called the "the '''root directory'''".
Learning how to issue Linux commands for navigating the Linux filesystem and manipulating directory and files are essential skills for Linux users and administrators.
In the Linux (Unix) OS, the "'''root directory'''" / is the starting directory, and other "child directories", "grandchild directories", etc. are created
The hierarchical structure resembles an "upside- down tree". There is actually a command called tree that can display a "tree diagram"!
