Directory Implementations
Unix
- Directories are implemented as a type of file.
- Each directory entry contains a file name and an inode (index node) number.
- The rest of the information associated with the file is located in the inode section of the volume.
- Every directory has an entry representing itself (.) and another entry representing its parent (..)
- Root inode is known.
Size, dates, ownership, protection, block pointers, etc.
