(13) File System II

The file system can be thought of as an upside down tree with "root" as the starting point.

The file system contains directories (folders) and files.

Directories can contain other directories as well as files. A directory is just a special type of file, containing file names and pointers to the internal data structures which hold the permissions, ownership etc. for the file. Directories are manipulated using special utilities.
