Commercial note-taking apps don't want to admit that a lot of structuring is already possible with the Operating System itself, in particular with a simple folder, where all filenames need to be unique and meaningful only within that folder context.
My filing strategy is not optimized for directly searching, but for browsing in context and seeing what is there. This is not just because I struggle to find the right search terms (or even what to ask Bing and Bard), but browsing fosters serendipity (think Luhmann) and learning by traversing my folder hierarchy and folder shortcuts.
Most of my files live initially on the desktop. From there they wander either to trash or into my folder hierarchy, or intermediately into a new folder on the desktop, If this folder is moved into the folder tree, I mostly fill its place on the desktop with a folder shortcut -- until it becomes stale.
