Introduction
For exchanging primary content with PLM systems, Creo Packages supports file types created in Creo Parametric. Creo Packages supports all file types while importing secondary content into Windchill PDMLink. However, while exporting content from Windchill PDMLink, it supports only those file types listed in the wpc_preferences.txt file.
Creo Packages also supports file types for Windchill PDMLink which are listed in the ObjectTypeDefinitions.txt file used while exchanging secondary content.
