Detect articles missing from a table of contents (toc.yml) file in DocFx

Sorry if this is an easy solution and I'm not aware.

Assuming source files are in a directory like this...

• Docs/articles/guide-1/article-1.md
• Docs/articles/guide-1/article-2.md
• Docs/articles/guide-1/article-3.md
• Docs/articles/guide-1/article-4.md
• Docs/articles/guide-1/article-5.md
• Docs/articles/guide-1/toc.yml

...and toc.yml looks like this:

 - name: Article 1
   href: article-1.md
 - name: Article 2
   href: article-2.md
 - name: Article 3
   href: article-3.md

Is there a way to see that article-4.md and article-5.md are in the same directory as toc.yml but not referenced in the file?

I know of scripts that identify image files that are un-referenced in a directory of Markdown files. I hope to accomplish roughly the same thing with un-referenced Markdown files.

Thank you if anyone knows how to do this, or has a suggestion on what I might pursue.

I have discovered now that one way is built in to DocFx. You can generate PDFs with an attribute of generatesAppendices as true. This produces a document called appendices in the directory the PDFs are output. It shows all files not linked up to a TOC. Add the .pdf extension.

Example usage in docfx.json:

    "template": [
      "pdf.default",
    ],
    "keepRawFiles": false,
    "generatesAppendices": "true",
