This has been effective to combine with an Areas of Responsibility and contextual approach. If nothing else, it’s given me a good opportunity to re-think a lot of my system without being too disruptive.
What I like about this approach is the use of [[progressive disclosure]] as a part of the file system. I find if I have too many disparate notes of different types grouped together in my file explorer, I find it distracting and hard to use.
Another thing I find helpful is the use of [[muscle memory]] for quickly jumping between folders and notes with the numerical values. It reminds me a lot of file structures on architectural and design projects.
I keep more information about my approach in my [[File Hierarchy SOP]].
