+# Folder View
+
+Folder view provides an additional view besides the timeline that is similar to a file explorer. It allows you to navigate through the folders and files in the library. This feature is handy for a highly curated and customized external library or a nicely configured storage template.
+
+You can enable this feature under [`Account Settings > Features > Folder View`](https://my.immich.app/user-settings?isOpen=feature+folders)
+
+## Enable folder view
+
+<img src={require('./img/folder-view-enable.webp').default} width="80%" title='Folder view enable' />
+
+## Usage
+
+You can then navigate to the view from the sidebar to explore the folders and files in your library.
+
+<img src={require('./img/folder-access.webp').default} width="30%" title='Folder view access' />
+
+<img src={require('./img/folder-view-1.webp').default} width="100%" title='Folder view' />
