This is my non - organisation system too... For everything which I don't have to keep decently for some external purpose. Even though I also love to organise stuff ha.

I did manage to get everything onto a 2TB harddrive, so now I have decades of irregularly organised chaos (more or less, I lost some of it several times through not backing up) all in one place - yay!

Also, despite all intentions to the contrary, I'm doing exactly the same thing with my newer devices lol (that's the hollow laughter of despair).
