Ah -- something I didn't notice earlier: you're using an old version of
Shotwell. The latest version (0.14.1) fixes numerous problems with RAW
support, including this issue. I highly recommend upgrading from
Yorba's PPA: https://launchpad.net/~yorba/+archive/ppa

Those extra files are generated by Shotwell because decoding the
.NEF file (or any RAW file) takes a lot of CPU power and time.
Also, there's two ways Shotwell can "develop" a RAW file: by
decoding the file or using one of its internal JPEG files.
Generally the internal JPEG file looks better because the camera has
tweaked it using various parameters (white point, exposure, etc.)
If you delete those files, Shotwell will regenerate them when you
next view that file in Shotwell. Note that the latest version of
Shotwell (0.14) will not generate so many of them; it's an old bug
that caused all those different versions to appear.

Thanks, Jim.
I tried deleting the three JPG files accompanying DSC_8937.NEF, and
the result was that DSC_8937.NEF became a "Missing File", according
to Shotwell, and it disappeared from its event.
After half a minute or so, it appeared to move from Missing FIle to
its event again, but double-clicking on it in its event window (to
view it) resulting in its going back into the "Missing FIle" slot.
I tried dragging and dropping the file from its folder in the file
system into Shotwell, and opted to leave it in place. The image duly
reappeared in the relevant event, but no JPG file has been generated,
and every time I double-click on it, it bounces back into the
"Missing File" box.
At no time since I deleted the JPG files has a new one been generated
in the relevant directory.
This is obviously not going to be as easy as I thought!
Could my difficulty have something to do with the fact that the
images I'm dealing with were shot entirely in RAW mode (i.e. not
RAW+JPG) on my Nikon D70?

Earlier this year I retired my elderly Dell PC running Ubuntu 12.04
in favour of a new iMac 27".
Virtually every application I was using on the Dell can be replaced
with a Mac-compiled version, but I'm still running Shotwell in a
virtual Ubuntu machine, storing all the images in a shared
directory on the Mac.
I've found that I've got a number of JPG versions of NEF files I'd
previously uploaded to the Ubuntu machine, and the migrated to the
Mac, for example:
DSC_8937.NEF is accompanied by
DSC_8937_NEF_embedded.jpg
DSC_8937_NEF_shotwell_1.jpg and
DSC_8937_NEF_shotwell.jpg
I'm currently using Shotwell 0.12.3 with Ubuntu 12.04 in a
Parallels VM.
Is it safe to delete any or all of these Shotwell-generated JPGs?
Will Shotwell generate a new JPG version if all that's left in a
directory is the raw NEF file? Or does it only generate this on the
initial import?
I don't _need_ the extra space at the moment, but I'd like to
dispose of an unnecessary overhead and reduce back-up requirements
if I can.
Thanks in advance,
Michael
