directory or sub-directory: �In DOS, Linux, and UNIX, a directory is a logical, user-defined division of a storage device.� For example, a user may divide a hard disk into several directories, with each directory used to store files that pertain to a certain task.� One directory may contain programs and documents for word processing, another for spreadsheet analysis, and another for database manipulation.� Newer operating systems use the word folder synonomously with directory.
