# Filebrowser [Filebrowser](https://filebrowser.org) provides a file managing interface within a specified directory and it can be used to upload, delete, preview, rename and edit your files. > When application is installed, a container will be launched with **root** privileges. > This is required in order to apply the correct permissions to the `Filebrowser` directories. > Afterward, the `Filebrowser` container will run as a **non**-root user (Default: `568`). > All mounted storage(s) will be `chown`ed only if the parent directory does not match the configured user. You can configure further the settings by using Environment Variables. See [Filebrowser Documentation](https://filebrowser.org/cli/filebrowser) for more information. Use the format `FB_OPTION_NAME` where the option name is the name of the option you want to set. You can also edit the configuration file `/config/filebrowser.json`. Note that the following options are already set and will always take precedence over the environment variables and the configuration file: - `FB_ROOT`/`--root` is set to `/data` (Any additional volume mounted will be under this directory) - `FB_PORT`/`--port` is set to `30044` (Or the port you configured in the installation wizard) - `FB_ADDRESS`/`--address` is set to `0.0.0.0` (It will listen on all interfaces **inside** the container) - `FB_DATABASE`/`--database` is set to `/config/filebrowser.db` - `FB_CONFIG`/`--config` is set to `/config/filebrowser.json` Also when a certificate is selected - `FB_CERT`/`--cert` is set to `/config/certs/tls.crt` - `FB_KEY`/`--key` is set to `/config/certs/tls.key`
