I swear this process couldn't be harder. I've tried about eight times to move my MacBook Air's Photos library from it to a WD NAS system (a 4TB My Cloud device). I've got a share created called Photos and I'm trying to drag and drop it over there. The best I'm getting is to 11.20GB out of about 15GB before I get some error 36. I'm in the middle of like my third attempted fix for that issue -- found an app that deletes DS Store files -- but I'm still wary. I've still got to figure out how to get 200GB of photos out of my Time Machine backup of my iMac that I probably killed last night thanks to the DisplayPort cable inside. I mean those are my damn pictures and videos. Since I'm likely just going to be a MacBook Air person now unless I get lucky and figure out how to fix my iMac, I've gotta get this Photos Library on an external drive thing figured out. Anybody else have these types of issues? It's a bitch moving huge files like this across a wireless network connection. It's bad enough when it's over USB. Also if anybody knows of a good set of reading on managing all sorts of media externally using a MacBook Air, I'd love to know about it. All of my TV comes in on my Apple TV boxes, and I have a bunch of movies stored on hard disks. It's fine watching when my MBA is awake and open, but that doesn't really work when it's not. I'm likely to invest in a new display to make clamshell mode a possibility, but I remember that not being a perfect solution about five years ago with a MacBook Air.
