Does 'Consolidate' in Apple Photos copy or move images?
I'm trying to backup a Referenced Apple Photos library (I know, I know, referenced libraries are a pain), and have come up with the idea of copying the library to a new location (external drive) and then consolidating to bring over all the original images. My question is, does this copy (I guess it does but want to be sure) the originals to the new location, or does it 'move' them (ie. copy and delete). I want to have a portable version (without iCloud!) but want to keep my original library intact and safe.
Thanks in advance for experience and advice!
