$UserBaseDirectory
 Usage
• $UserBaseDirectory gives the base directory in which user-specific files to be loaded by Mathematica are conventionally placed.
Notes
• $UserBaseDirectory returns the full name of the directory as a string. • Typical values are:
C:\Documents and Settings\username \Application Data\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 ones of $BaseDirectory. • New in Version 5.
