Uh, I don’t know that

However you go about it, keep it simple. If it’s complicated or a chore to do, compliance will likely fall off and you might not maintain it.

I do the YMD thing with folders, but fail to do the text file; it’s not a deal killer for me, but there are times we have to figure out what on earth we were doing. We can get a lot of contextual clues from the photos themselves. Depending on what you’re shooting, establishing shots can be really helpful.

Folders get YYYY-MM-DD, files get whatever they get. A simple text.txt file get placed in each folder describing the photos of that day.
