Check that the entire folder contents have copied correctly before deleting the originals.
There have been (rare!) reports of problems caused by canceling the transfer, so it’s best to let it complete uninterrupted. One warning-don’t press the X in the Activity Center to cancel this move. (Existing folders can only be selected if they’re empty, or by importing one of the photos in that folder.)
Navigate to the new location and create a new folder, or select an existing folder where you plan to place the photos.
