Thanks so much, J.A. I will try this. In the meantime, searching the previous posts (which I should have done before I posted) gave me this answer ---
"I use SkyDrive, it being more generous in providing 7 free gigs compared to DropBox's 2gigs ( further storage purchases quite reasonable in price also) I hope I am not telling something you already know.
Simply download the iPad's SkyDrive App and then onto your PC the SkyDrive App suitable for that (I have Win7 recently updated to Win8) and it's a simple matter to sync all your data back and forth between the two devices. Just copy/paste or drag and drop stuff into your PC's SkyDrive file and it will appear in your iPad's SkyDrive App.
Regards, Andrew"
and since I do use OneDrive (formerly SkyDrive), I tried it and it works!
