Think of the Utilities folder as the toolbox for your notes.
These notes support your other notes.
Imagesautomatically get added to “Images” folder (and any other attachments you bring into your vault).Templateswill be stored in a “Templates” folder as well.
You may also want to keep specialty files here like:
Canvasfiles (which are .json files)Excalidrawfiles (which are remarkably still regular markdown .md files)
