$UserBaseDirectory

$UserBaseDirectory
gives the base directory in which user-specific files to be loaded by Mathematica are conventionally placed.

MORE INFORMATION

$UserBaseDirectory returns the full name of the directory as a string.

Typical values are:

	C:\DocumentsandSettings\username\ApplicationData\Mathematica
		Windows
	~/Library/Mathematica	Macintosh
	~/.Mathematica	Unix

The value of $UserBaseDirectory can be specified by setting the MATHEMATICA_USERBASE operating system environment variable when the Mathematica kernel is launched. It cannot be reset from inside the kernel.

Typical subdirectories of $UserBaseDirectory are:

	Applications	Mathematica application packages
	Autoload	packages to be autoloaded on startup
	FrontEnd	front end initialization files
	Kernel	kernel initialization files
	Licensing	license management files
	SystemFiles	general system files

These subdirectories are, if possible, created automatically the first time Mathematica is run by a given user.

Appropriate subdirectories are automatically included on $Path.

The subdirectories of $UserBaseDirectory are given in $Path before the corresponding subdirectories of $BaseDirectory.
