I had to send my camera away to be checked after dropping it and when it came back the file continuous numbering was all to cock. folder 988 image 9876 or something like that.
Well ok format a CF card and set camera to auto reset and I am back at folder 100 IMAGE 0001
Now after reading a thread on POTN and a bit of thinking, I now have a solution to the problem if this happened to anyone.
Format your CF card and copy your last image from your computer back on to the CF card, lets say IMG_6838.CR2 place in camera and your back to normal, next shot will be IMG_6839.CR2
Ah but I did not think of this and have taken a few hundred shots since I reset my continuous numbering so my file count should be IMG_7203.CR2 but it is IMG_0230.CR2 . Well not a problem, do as before and copy an image to the CF card , then rename to IMG_7203.CR2 and put the CF card back in your camera your next image will be IMG_7204.CR2
