Hi folks, at some point in the next few months I will be handing back my MacBook to my employers. I'm trying to get all my photos backed up efficiently for transferring to my new personal MacBook. Apparently I have 200gb+ in my "Pictures" folder. Now 70gb of that is in Photos, which is where I store stuff I really want to keep (and the family can access via iCloud). Now the majority of those will have been exported from Lightroom. I know, I know, I should have deleted them from LR when I exported to Photos! Is there any tool which could find me the files (by filename - they could be JPG, RAW or TIFF) in the Pictures folders which are also in the Photos library? Then I could remove anything which is in both places and probably save myself about 50gb of storage. That matters with a 512gb disk!
