[Justin Lange] " Or can I delete all shots not marked on the camera before I offload and import?"
You can delete them on camera, so the folder/files structure reflects the changes.
if you delete them manually in the computer, you might have problems when importing.
I don't work with PP, but with FC, but as a rule of thumb is recommended to keep the original card structure. Many of us have learnt the hard way no to mess with it.
