+            This endpoint allows listing files in a user's data directory, with options for recursion,

+
+            Query Parameters:
+            - dir (required): The directory to list files from.

+            - full_info (optional): If "true", return detailed file information (path, size, modified time).
+            - split (optional): If "true", split file paths into components (only applies when full_info is false).
+
+            Returns:
+            - 400: If 'dir' parameter is missing.
+            - 403: If the requested path is not allowed.

+            - 200: JSON response with the list of files or file information.

+            - full_info=true: List of dictionaries with file details.
