Suppose, for the sake of argument, that you had deleted some clips from your card collection to save space and now you had a LOT more space and were thinking that maybe you would like them back. And suppose you had done this for, say, a thousand cards. Is there a efficient way to get the missing clips back? Or do I need to delete each entire card and download it again??? 😳

Select cards in Batches of 50 to 100 at a time.
Right click on the trash can Icon and Selected Check for Updates
It will download the Missing clips.

I'd even do 20 cards at a time..
that way you don't get stuck for days, downloading.
