Two options that make sense:
- Use the attachements package to handle the attachment of files to you objects. This is document throughout the toolkit, take a look at forums how this works.
- Alternatively you could store your files directly with the object itself. Contacts makes use of this behaviour at /contacts/www/files*. You could copy paste these files to your application and just replace party_id with mfp_note_id and that should do the trick.
