Adding and Updating Data Formats
When content files are added to a content holder object, the format of the file (based on the file name extension) is set automatically upon upload. The available formats are stored as DataFormat objects in the system.
In some cases, you may need to augment or change the existing data formats to accommodate additional MIME types associated with your enterprise data.
* 
Any changes made to existing data formats or any new data formats that you add should be treated as customizations to your code.
A data format:
Sets the MIME type when a file is downloaded.
Supplies the icon that will represent the object in browser displays.
Informs the user of the file format.
For details how to customize data formats, see the Windchill Customization Guide.
