What is an ID?

On the forum, user cobblepot raises the question of how much a Johnny.Decimal ID should contain, and whether it should contain subfolders, and if so how many.

My thinking on this has changed significantly over the years. The site needs a proper refresh, which will take time. It's next on my list.

Until then, this short video hopefully clarifies my thinking, and answers some of cobblepot's questions directly.
