I would like to suggest a way for the Adobe Photoshop Lightroom Catalog to be more incidental in its file structure. I'll explain. I currently have the cloud based service Copy. Through them I have 250GB of cloud storage. What I am trying to do is sync my catalog from my laptop to my desktop. I'm tired of editing on one machine and having to start over or convolutedly export and import each session at a time. The problem i have is that my catalog is 1.7GB. So if i open Lightroom and turn a single photo black and white and close lightroom, Copy is uploading the entire 1.7GB of catalog information. If somehow the Lightroom catalog could be broken up into folders, perhaps by the date accessed or the date of each corresponding file's "photographed" date, then every time i make a change only minor differential information will have changed and Copy doesn't need to upload 1.7GB of data every time. I realize the location of the stored files are of concern. People can either use external disks, or in my case i'm using the excessive storage i have through Copy. The catalog itself could also work for the cloud storage you already provide for Creative Cloud users. I would have gladly stored my catalog on the Creative Cloud but since i have 250GB with Copy I'm also importing the photos themselves onto Copy so the libraries can be the same too.
