Or you use something like Obsidian, Logseq, Notion and so on that have already abstracted this problem away. You rename a file or move it to some subfolder and every single reference to it gets auto-updated without you having to do anything. I'd argue that this sort of interlinking flexibility (alongside easy-to-use plugins) is what separates the current era of note-taking apps over alternatives that people seem to (ab)use: a folder of Markdown notes edited via VSCode, a Google Docs folder, or even a static site generator.
