Thank you all for your comments.
The reason I thought I`d lost my butterfly photos is I started to have conflicts on the computer (windows explorer is not responding) plus other problems, I thought it was due to a memory upgrade I did, so I had the memory tested it was good, so while I was trying to back up the photos (23 hours 1 gig) I searched for a solution it turned out to be the internet security I use, when I cleared it off the computer it started to work perfectly with no problems back up reduced to a few mins and no more problems at all, so at the moment the computer security is windows fire wall only, Now I have find a good light weight antivirus...........so don`t forget to backup like I did..................I still use the same internet security on my other laptop with no problems.
