Are you looking for Implementing Support for Custom File Formats?
Applications that are able to open specific document or file formats may register those formats with the system. When the system or another application needs to open a file, it can hand that file off to your application to do so. In order to support custom file formats, your application must:
- Register the file types your application supports with the system.
- Implement the proper methods to open files (when asked to do so by the system).
