I have about 11,000 photos, about 40 GB, of photos in my photo library which are from my work. Now that I'm pretty much retired I'd like to decrease the size of my photo library by moving these (in their albums folder organization) off onto an external drive. My initial searching on the subject has turned up several points which I am finding hard to believe. Point #1, exporting a group of Albums is not supported. Point #2, if I create another Photos library, where one can in principal open that library and import selected photos from the main library, (then delete that from my main library after verifying it has worked). EXCEPT this doesn't work if one has ICloud photos turned on. And, "Keywords are not imported". I have numerous slide shows, about 40, another fair bit of data, which I'd also want to move off to the 'work' library on an external drive. In the old days, when I was a PC guy, I'd just simply copy the dang files over to the other drive. Does anyone have experience on how to accomplish this task? Perhaps there is third party software? Thanks all.
