These days, a shallow folder system. I have an electronica folder, and a Blanck Mass folder that definitely would go in there but that is full enough to stand on it’s own. Actual taxonomic organisation would take way too many clicks, but flat organisation can result in trouble finding things, and just looks like you’re a slob. (Although I’m guilty of having unsorted hoarder folders for things I only needed once, too)

There’s probably a rule of thumb for optimal fanout on each GUI folder, related to our visual processing. Hmm. I wonder if there’s a way to make the tree self-balancing as well.
