FilledSmallSquare 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.

FilledSmallSquare Typical subdirectories of $BaseDirectory are:

FilledSmallSquare These subdirectories are, if possible, created automatically the first time Mathematica is run.

FilledSmallSquare Appropriate subdirectories are automatically included on $Path.

FilledSmallSquare The subdirectories of $BaseDirectory are given in $Path after the corresponding ones of $UserBaseDirectory.

FilledSmallSquare See Section 2.12.4 and Section A.8.2.
