# Single type

FileBird Document Library allows you to add **multiple folders to a single list**. However, once the library is published, it displays all files in bulk, not hierarchical.

In order to bulk select folders, just press **Shift** or **Ctrl** key while selecting folders, just like how it works when you select multiple files on your computer.
