Question: Photos referenced library file size bigger than original image folder
I am running latest High Sierra on a Mid-2015 5K iMac. I have a folder of raw images with a file size of 432GB on an external thunderbolt drive. I have the same folders referenced in several different editing/DAM programs, this way I can train myself on different techniques without using more storage than necessary. I have been attempting to import the images into Apple Photos app as referenced images as that is the way my family would like to access the image. My belief is as with Aperture and iPhoto I could keep the smaller catalogue/library on my internal drive and thereby not take up more room on my internal.
The issue is when I attempt to import the images into Photos with the import photos to the library open unchecked I get a warning message stating Insufficient Disk Space Additional 1.32TB of free space needed to continue...
Everything I do, including creating new libraries, has the same result!
Any ideas? I understand Photos will create preview images, but 1.32TB from an original 432GB of images... :-/
Having scoured the web for an answer I have reached the conclusion, which I hope is wrong, that this is the way Photos works and it does not treat referenced images in the same way any other editing/DAM application does.
Any thoughts on this issue???
Thank you :-)
