A static file server. It works by appending the request's URI path to the [site's root path](/docs/caddyfile/directives/root). By default, it enforces canonical URIs; if necessary, requests to directories will be redirected to have a trailing forward slash, and requests to files will be redirected to strip the trailing slash.
Most often, the `file_server` directive is paired with the [`root`](/docs/caddyfile/directives/root) directive to set file root for the whole site.
- **root** sets the path to the site root for just this file server instance, overriding any other. Default: `{http.vars.root}` or the current working directory. Note: This subdirective only changes the root for this directive. For other directives (like [`try_files`](/docs/caddyfile/directives/try_files) or [`templates`](/docs/caddyfile/directives/templates)) to know the same site root, use the [`root`](/docs/caddyfile/directives/root) directive, not this subdirective.
- **hide** is a list of files to hide; if requested, the file server will pretend they do not exist. The active configuration file will be added by default. Specifying a file name without path will hide all files with that name; otherwise, a prefix match will be attempted, and then a globular match.
- **<template_file>** is an optional custom template file to use for directory listings. Defaults to the template that can be found [here in the source code <img src="/resources/images/external-link.svg">](https://github.com/caddyserver/caddy/blob/master/modules/caddyhttp/fileserver/browsetpl.go).
The `file_server` directive is usually paired with the [`root` directive](/docs/caddyfile/directives/root) to set the root path from which to serve files:
