 The [`glob()` loader](/en/reference/content-loader-reference/#glob-loader) creates entries from directories of Markdown, MDX, Markdoc, JSON, YAML, or TOML files from anywhere on the filesystem. It accepts a `pattern` of entry files to match using glob patterns supported by [micromatch](https://github.com/micromatch/micromatch#matching-features), and a base file path of where your files are located. Each entry's `id` will be automatically generated from its file name. Use this loader when you have one file per entry.
 
-The [`file()` loader](/en/reference/content-loader-reference/#file-loader) creates multiple entries from a single local file. Each entry in the file must have a unique `id` key property. It accepts a `base` file path to your file and optionally a [`parser` function](#parser-function) for data files it cannot parse automatically. Use this loader when your data file can be parsed as an array of objects.
