That would be really cool and a great enhancement.
I think photos are what most have as raw data that need to come from files or get written to file for that matter. But of cause there are other types of raw data as well.
What could be done is to have a unique naming scheme for the files as "useridentifier-attribute.raw" that way it would be easy for the driver to know what to do as well as it would be fairly easy for the person/process that places or reads the files.
But I'm sure you already got some idea on how to solve this :-)
