From http://www.linfo.org/root_directory.html
"The root directory is the directory on Unix-like operating systems that contains all other directories and files on the system and which is designated by a forward slash ( / ).
The use of the word root in this context derives from the fact that this directory is at the very top of the directory tree diagram""
