Directory Definition. The term directory is used in a computer software context to refer to what appears to the user to be a container or folder1 that can hold files and other directories. A file is a named collection of related data that appears to the user as a single, contiguous block of information and that is retained in storage.

The default drive is the disk drive the computer accesses unless you specify a different disk drive. Likewise, the default directory is the directory the operating system searches unless you specify a different directory. The default can also be an action that a device or program will take. For example, some word processors generate backup files by default.
