You can also use `File()` with `UploadFile`, for example, to set additional metadata:

{* ../../docs_src/request_files/tutorial001_03_an_py39.py hl[9,15] *}

## Multiple File Uploads { #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`:

	// 1. Initiate 2 uploads for the same object
	// 2. Upload 2 parts for the second upload
	// 3. Abort the second upload.
	// 4. Abort the first upload.
	// This will test abort upload when there are more than one upload IDs
	// and the case where there is only one upload ID.

	// construct HTTP request to initiate a NewMultipart upload.
