Exclude Files and Folders from Front Matter CMS

To prevent Front Matter CMS from including specific files and folders, you can provide the paths to be excluded in excludePaths under frontMatter.content.pageFolders:

{
  "frontMatter.content.pageFolders": [
    {
      "title": "Posts",
      "path": "[[workspace]]/content/posts",
      "previewPath": "posts",
      "contentTypes": ["Post (default)"],
      "excludePaths": [
        "_*.*" // Exclude all files starting with an underscore
      ]
    }
  ]
}

I use this to exclude _index.md files from Front Matter.
