Directories Directory

Directory is a book containing an alphabetical or classified listing of names, addresses, and other data, such as telephone numbers, of specific persons, groups, or firms.

In computing, a directory, catalog, or folder, is an entity in a file system which contains a group of files and other directories. A typical file system contains thousands of files, and directories help organize them by keeping related files together. A directory contained inside another directory is called a subdirectory of that directory. Together, the directories form a hierarchy, or tree structure.

If you imagine the computer's file system as a file cabinet, high?level directories may be represented by the drawers, while lower?level subdirectories may be represented as file folders within the drawers.
