Directory: In the context of computing, a directory is a file system cataloging structure that contains references to other computer files and possibly other directories. On many computers, directories are known as folders. In operating systems, directories are used to organize files in a hierarchical structure, providing a convenient means to access data stored within the system. Additionally, in networking, a directory refers to a service that stores, organizes, and provides access to information about network resources and users, such as a Lightweight Directory Access Protocol (LDAP) directory.
