The Directory Index

• A directory is an inode of type "directory", whose data contains the list of files found in the directory.
• Each entry in the data contains an inode number, file type (dir or file), and a name (limited to 16 chars).
• We don't keep entries for "." and ".." on disk - the file system's code adds these entires "on-the-fly" at run-time.
