Thank you, Tristan - so one last question about back-ups. When I create a project, add a shoot to it, process the files in the Customize tab (in project view), then select File > Project Database > Create a Back-up, this will then save the NEF files (just those in the current project?) to a destination of my choice? What about the sidecars, as I see there is an "export sidecars" option in the drop down File menu - or do they go along with the backup anyway?
When I do a restore of that back-up - it is just a restore of the one project then, right?
I think I may be beginning to see the light! ..or not!
