Thanks for the help. 11Fan, thats a nice tip. I tried that and got lots of images up that were removed, and I thought I had the missing files for a moment, but it wasn't to be. Of course I should have saved them to the external drive. This wasn't the first time this has happened to me, and I have for many years been backing my aircraft pics to an external drive, I just never seemed to get round to doing everything else. I will just have to accept that they are lost. It's annoying, as I had some nice pics that I was intending to use for camera club competitions. Just spent the last two days getting rid of the junk from my files, and putting the rest on the external drive.
Thanks again
Danny
