+## Multiple file uploads
+
+It's possible to upload several files at the same time.
+
+They would be associated to the same "form field" sent using "form data".
+
+To use that, declare a `List` of `bytes` or `UploadFile`:

+```Python hl_lines="10 15"
+{!./src/request_files/tutorial002.py!}
+```
+
+You will receive, as declared, a `list` of `bytes` or `UploadFile`s.

 ## Recap
 
 Use `File` to declare files to be uploaded as input parameters (as form data).
