This message is sent by the Filer to ask an application to load a file, or by a task in response to a Message_DataSaveAck message.
Notes
When replying to a Message_DataSaveAck message, the data-saving task should write its data to the temporary file specified, and reply by sending this message.
The reply to this message should be sent as a User_Message_Recorded so that if it returns unanswered, the sender can delete the temporary file and report an error.
Possible responses from data-loading task:
- Task sends Message_DataLoadAck message (file successfully loaded)
- Task does not reply (error loading data / not interested in filetype)
