Secondary Content, Windchill Only
This option allows you to export the secondary content of the Creo Parametric data and is applicable for Windchill only. By default no secondary content is included in the package.
You can specify a list of secondary content categories along with extensions for export, separated by commas. For information about supported file types for exchanging secondary content, see Supported File and Object Types.
The following example specifies secondary content in a category:
export.secondary.content.category=@"*.*:@INSTANCE_ACCELERATOR_
FILE,@"*.step":@EXPORT
* 
When specifying a secondary content name, it has to be based on the internal name, and not the display name. This is to ensure that the category name does not depend on the locale of the client.
The internal name can be found at: <Windchill>/codebase/com/ptc/windchill/cadx/cfg/default/contentcat.ini
* 
To specify extensions, use “any” or an asterisk (*).
