Is it possible to replace masters with versions without going through the process of exporting and importing?

Question

Is it possible to overwrite the master files with the versions without having to go through the entire process of exporting and importing back the images?
Thnx in advance

Answer 1

A small refinement if you shoot RAW. Remember, no RAW file can ever be edited or rewritten. Thus, in the old days, the flow was:
RAW>TIFF/PSD and you ended up with two large files. (This is why some folks used to delete the RAW Masters.)
With Aperture the flow is something like:
RAW+Version(s) Only the Version is only 30 KB. (There is, of course, additional overhead of Thumbs and Previews, but, depending on your settings, this is only a fraction of the size of a TIFF or PSD.)
You question goes right to the heart of the concept of a non-destructive workflow. With Aperture you always preserve your original Master file; the only things that are ever at risk are your edits (called Adjustments). Ironically, this is even more valuable if you shoot JPEG or TIFF as those files could be rewritten.)
Aperture goes to great lengths to give you the best of both worlds; you always have the Master to revert to and your "edits" take up very little disk space. And you don't have to waste time trying to sync folders of RAW, TIFF, and JPEG. Similarly, you never have to worry about resizing images, changing color spaces, or any number of other things that get locked into an image file when you use a destructive workflow.
Remember, Aperture will happily Export files in any format you may need. Export 'em, use 'em, delete 'em - your Masters are still safe in Aperture.
