-+ **baseurl** is the URL where you will access the File Manager interface. Defaults to `/`.
-+ **scope** is the path, relative or absolute, to the directory you want to browse in. Defaults to `./`.
-+ **path** is the database path where the settings that aren't included in the Caddyfile will be stored. By default, the database will be stored on `.caddy` folder and its name will be an hashed combination of the host and the `baseurl`. It is **highly** recommended to set this option. Otherwise, whenever you change the host or the `baseurl`, your settings will be lost or you will need to point to the previous database.

+`path` is the database path where the settings will be stored. By default, the database will be stored on `.caddy/filemanager` folder and its name will be an hashed combination of the host and the `baseurl`. If you use a relative path it will be relative to `.caddy/filemanager`. Despite being optional, it is **highly** recommended to set this option in order to keep the settings when you change the `baseurl` and/or the hostname.
