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 document and settings for programs.
Different Implementations [change]
Unix, Linux and the like [change]
It can be written as ~.
Microsoft Windows [change]
Since Windows 95 there is a directory called My Documents. It was introduced together with My Computer. It helps the users locate their files. Since Windows 2000 it is in the user's profile directory Documents and Settings\username. So a user fred will find his files in Documents and Settings\fred\My Documents. In Windows Vista the directory has lost the My, and is simply called Documents. Other directories, which are similar, may exist. They are called My Music, My pictures and My videos.
Mac OS X [change]
In Mac OS X, the home directory is in /Users.
