+
+#### File duplication
+
+When you duplicate a file, the editor creates a new file with the same content and adds a `-copied-N` suffix to the filename, where `N` is an incrementing number. For example, duplicating `quickstart.mdx` creates `quickstart-copied-1.mdx`. If you duplicate again, it creates `quickstart-copied-2.mdx`.
+
+The duplicated file includes all the original content and is automatically added to your navigation in `docs.json`.
+
+#### Folder duplication
+
+When you duplicate a folder, the behavior depends on the structure of the files inside:
+
+- **Files share a common folder**: If all files in the folder share the same parent directory (for example, `guides/getting-started/intro.mdx` and `guides/getting-started/setup.mdx`), the editor duplicates the entire folder structure. The new folder gets a `-copied-N` suffix (for example, `guides/getting-started-copied-1/`), and all file paths are updated to reflect the new folder name.
+
+- **Files in different folders**: If files don't share a common parent directory, the editor creates individual duplicates of each file with the `-copied-N` suffix and updates the navigation accordingly.
+
 ### Organize your navigation
 
 Edit your `docs.json` file to add new pages and remove deleted pages from your site navigation. See [Navigation](/organize/navigation) for more information on how to organize pages.
