# Module "System > Settings"

> [!NOTE]
> **Changed in version 14.0**
>
> This module has been moved from **Admin tools** to **Settings**.
> See also: [Feature: #107628 - Improved backend module naming and structure](https://docs.typo3.org/c/typo3/cms-core/main/en-us/Changelog/14.0/Feature-107628-ImprovedBackendModuleNamingAndStructure.html#feature-107628-1729026000).

Global configuration can only be changed by backend users with
[System Maintainer privileges](https://docs.typo3.org/permalink/t3coreapi:system-maintainer@main).

Use the backend module **System > Settings** to access the
different configuration options:

Changes made in this module are written to file `config/system/settings.php`.
They can be overridden by configuration in file `config/system/additional.php`
in which case they cannot be changed from the TYPO3 Backend.
