A directory is a collection of organized files and/or folders that are stored on a computer or a network. Directories are often used to store related files and help to keep the computer or network organized. They can also be used to manage access to files and control who can view, edit, or delete files. Directories can be thought of as a type of file that contains other files and directories within it, allowing for a hierarchical organization of information. In computing, a directory is often referred to as a folder.
