Unfortunately it was literally a beginners error on my part! I’m still learning but this forum has been great, so thanks. I copied most of it ok but for some reason the second lot I just copied the contents of the clips001 file but missed the journal folder and index.mif. I will try the app mentioned above (I am a poor runner so more expensive software isnt an option unfortunately!)
If I can get my hands on the camera and card again, would it repair the file if I copied the clips back on to it? I might be able to get hold of it to try that out!
We live and learn!
Thank you
