Directory

Directory is a list of items, things, persons, places, telephone numbers etc. For example, a telephone directory. Directories can be in form of books, booklets, or electronic files etc. Sometimes directories can be blank having only the plan, system or structure for future recording of items therein, which is generally available in the form of a blank notebook. We can also have such electronic directory-notebooks.

In history, we had also a directory in France between 1795 and 1799 having executive powers of the state. It was called directory because the group was comprised of five directors.

In computer science or web application, it is a folder containing other folders (subdirectories) or files.
