The Configuration file for the Max plugins is MaxNifTools.ini and is delivered to the plugcfg directory of 3ds max. The file is plain text and a standard Microsoft INI file which uses the conventions of that format.
Sections
System
The System section holds information about the how all of the plugins behave and what Games are known to the importer.
MaxSDKVersion - This is the version of the SDK displayed to the 3ds max when the plugin is first loaded. Most users will never ever need to modify this but it was added as a potential workaround to trick older versions of max to load the plugin. The options are (0 - AutoSelect; 0x17700d00 - Max6, 0x1f401100 - Max8) with the default always set to AutoSelect.
ShortDescription - ShortDescription the description of the plugin that is used in File Import/Export dialogs.
KnownApplications - KnownApplications is a semicolon separated list of games that are have there own sections below in the configuration file. User is a special case that will always exist and is just a default place holder so that there is always at least one game in the list.
Reparse - Reparse tells the plugins to reparse the game sections below on every import/export. If the game is configured to use a Texture directory cache then that will be reset and scanned again next time an import or export occurs.
Website - The primary website to goto when www.niftools.org is selected. Probably no need to ever edit this.
Wiki - The wiki page that contains the help for these tools.
