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.
