+
+=====
+Files
+=====
+
+.. sectionauthor:: John Molakvoæ <skjnldsv@protonmail.com>
+.. versionadded:: 27
+
+Since Nextcloud 27, the files app has been rewritten to use new standards
+and frameworks. This means that the old documentation is no longer valid.
+We will update and document the new files app APIs and methods here.
+
+.. note:: Some external libraries offers in-depth technical documentation.
+    Please have a look at the following:
+
+    * https://github.com/nextcloud/nextcloud-files (`documentation <https://nextcloud.github.io/nextcloud-files/>`__)
+    * https://github.com/nextcloud/nextcloud-upload
+
+
+Router
+^^^^^^
+
+To change views and parameters of the current Files app, we expose the router.
+This directly maps to the Vue router. You can check their own `documentation <https://router.vuejs.org/guide/essentials/navigation.html#navigate-to-a-different-location>`__ to
+better understand the methods.
+
+.. code-block:: ts
+
+  /**
+   * Trigger a route change on the files app
+   * 
+   * @param path the url path, eg: '/trashbin?dir=/Deleted'
+   * @param replace replace the current history
+   * @see https://router.vuejs.org/guide/essentials/navigation.html#navigate-to-a-different-location
+   */
+  goTo(path: string, replace: boolean = false): Promise<Route>
+
+  /**
+   * Trigger a route change on the files App
+   *
+   * @param name the route name
+   * @param params the route parameters
+   * @param query the url query parameters
+   * @param replace replace the current history
+   * @see https://router.vuejs.org/guide/essentials/navigation.html#navigate-to-a-different-location
+   */
+  goToRoute(
+  	name?: string,
+  	params?: Dictionary<string>,
+  	query?: Dictionary<string | (string | null)[] | null | undefined>,
+  	replace?: boolean,
+  ): Promise<Route>
+
+
