About File Types
The majority of Creo Parametric files are object files that store information about an object. Other files created in Creo Parametric are object-dependent, temporary files that contain information that may have been output by you, or created as a quick way to retrieve data without regenerating the object, such as the .ptd file for Family Tables.
You can remove temporary files from the system (identified with an asterisk in the following table), but you must never delete object files.
In the following table of file-naming conventions, words like sectionname, partname, and filename indicate the name you enter at the prompt for sections, parts and data files, or the active object used to create the file (for example, partname.inf).
