How do I move (not copy) photos from Camera Roll to a new folder?

That is how it currently works. When you copy photos into the new albums that you've created directly on your iPad then you are effectively just creating pointers to those photos, so if you delete the original photo you will also be deleting all pointers to it. You could either need to copy them to your computer, organise them on there and then re-sync those fodlers/albums back to the iPad, or there are third-party photo management apps such as Photo Manager Pro which give you more control over your photos.

Yes, if you create a folder on iPad and copy photos over, you are only creating a link to the photos in Camera Roll the design idea behind this is to save space.

What you can do is save the photos on computer, create a folder (events) and sync the photos back to iPad.

Now you have truely two copies, you can delete the photos from camera Roll if that what you want.

You are missing nothing at all. That is the way this whole thing works on the iPad Photos App.

The folders/albums that you creat on the iPad only contain a shortcut or a pointer to the original photo. You can't put a copy of the photo into a new album and you cannot move the original photo to another album.

Albums that are created in the Photos app are local albums for photo organization on the device only. They cannot be imported onto your computer either, because photos do not really exist on those albums - only the shortcuts to the photos.

It is infuriating that Apple puts us through such contortions just to do such a simple thing as delete a photo. Thanks for the explanation! It make sense, though it suggests that Apple (like Microsoft) hasn't the slightest interest in making life easy for its customers. I've played around with ITunes, ICloud, syncing and all the rest in an effort to get my IPad to play nicely with my pc, and I am fed up with how tough they make it. In any event, I just downloaded Photo Manager Pro. That seems to have done the trick!
