Home directory
In computing, a home directory is a special directory (or location in the File system, Apple calls directories folders). Very often, there is one such home directory per user. Some users, which were created by the system and usually do not log in, do not have such a home directory.
A home directory is used to store personal files of the respective user, including written documents and settings for programs.
