- The files are organized by strong relative files in the same directory. In a hierarchical file system a directory contains inside another directory, called sub directory.
- The terms parent and child are often used to describe the relationship between sub directory and directory in which it is catalogues the data being the parent.
- The top most directory in such a file system which does not have a parent of its own is called the root directory.
