Need help. When I move a RAW file to any location outside Aperature 2, the file automatically changes to a JPG. I can't find in prefrences any way to prevent this. Also, when I move RAW files to HD, the files are aslo changed to a JPG. If I export as a "project", then I can not see the thumb nails on the external drive and must open entire folder back in Aperature 2 just to see what the content of the files are. The only way I found to save phots in thier native format is to copy over the entire Aperature 2 library. (5 hours)This of course, is not pratical for saving or adding futue files as i run into the same problem as before. How can I save a copy of a file in it's native format when moving to my external drive?
