Max uses settings and folders tucked away in various windows locations. Sometimes it can be a little tricky to track things down, and even navigating the windows explorer can be tedious if the file is buried in a deep folder structure.
Typing this code into the maxScript Listener will open the Windows Explorer at the folder containing the 3dsMax.ini file.
shellLaunch ( GetDir #maxData )
(note: you can inspect backup and restore 3dsMax.ini settings with this MAXScript)
The GetDir command is pretty simple. It just requires the right name for the 3dsmax folder.
GetDir <filetype_name>
where <filetype_name> maybe one of the following MAXScript 3ds Max System Directories
