I agree that the Nikon raw format .NEF should be in the photo group. It makes it very difficult to go back and forth between the NEF copy in the “other” group and the photoshop edit of the same photograph in the Photos group.
I am a professional photographer and bought this hard drive with the backup up software to manage and protect my 10,000 photographs.
Your post sounds more like an Idea or a Feature Request. The best place for this is in our Ideas Lab. This way someone from WD will be sure to see it. However, I would search first and make sure that there isn’t another idea similar to yours that you could add your post to and vote on.
