RAW Images

[JohnS]

I have been using cam2pc very successfully to download and rename JPEG images for several months. Then I thad a few RAW (dng) images produced by my Pentax K5 camera and cam2pc completely ignored them. It was as if they weren't on the memory card, but another program, Helicon Photosafe displayed them alongside the JPEG's. What am I doing wrong? I'd dearly like to continue to use cam2pc but this is a major stumbling block.
