UNIX files don't actually reside inside directories. A directory is really a file that contains references to other files. The directory holds two pieces of information about each file:
- Its filename. - An inode number which acts as a pointer to where the system can find the information it needs about this file.Filenames are only used by the system to locate a file and its inode number. This correspondence is called a link. To the system, the file is the inode number. Multiple filenames can be used to refer to the same file by creating a link between an inode and each of the filenames.
