Where do I find the Samsung S5 private folder in adb?

So my dear old Samsung S5 has died in a bootloop. But before I either wipe it or trash it I wanted to recover my old photos. I've managed to pull most of them by going into their folders and then pull them in adb shell. However, some photos are in the private folder and I don't know where it is. So my question is: Where do I find the private folder in the Samsung S5 with adb? The Dr.fone software managed to pull some of them, so there should be some way to reach them I think.
