If you right-click it and select , the instances involved in this file generation will be automatically displayed in the References view.The generation also produces the corresponding metadata files:.dllpdp (for a relational Block) or a .txtpdp file (for the other Blocks). These files can be viewed in the Package Explorer view. They must not be edited but must be assigned the same version number as the other generated files.
