I started out using more folders but found that it was imposing structure on my notes rather than letting the structure emerge from my notes. So I moved everything into the root folder except for 3 types of notes/assets that I maintain in folders
root
- journal
- daily (all my daily notes)
- weekly (all my weekly review notes)
- resources
- attachments (all images, PDFs, etc)
- reference (any materials needed like mermaid docs, flatui colors, Markdown documentation)
- templates (all my templates to be included or used at note creation time)
- sources (all raw source notes downloaded using MarkDownload)
This effectively keeps some of the noise down in the main root directory as daily and weekly notes grow pretty quickly, and attachments aren’t directly viewed but rather in context of notes
One additional benefit of keeping everything in the vault root directory is that linking (mostly) works in 1Writer which is what I am currently using on iOS
