6) Register  our own file data type.

Put a ProgId inside your component. FileId should refer to theId attribute of theFile element describing the file meant to handle the files of this extension.

To assign an icon to this file type, you have to specify where the icon should come from:

<ProgId Id='AcmeFoobar.xyzfile' Description='Acme Foobar data file' Icon='Foobar.ico'>

or, if the icon comes from an executable or resource file containing several icons, you can specify which one:

<ProgId Id='AcmeFoobar.xyzfile' Description='Acme Foobar data file' Icon='Foobar.exe' IconIndex='1'>
