You can define files to be uploaded by the client using `File`.

/// info

To receive uploaded files, first install <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>.

Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and then install it, for example:

```console

        listen       9000;
        listen  [::]:9000;
        server_name  localhost;

        # To allow special characters in headers
        ignore_invalid_headers off;
        # Allow any size file to be uploaded.
        # Set to a value such as 1000m; to restrict file size to a specific value
        client_max_body_size 0;
        # To disable buffering
        proxy_buffering off;
        proxy_request_buffering off;

	// uploadID to be used for rest of the multipart operations on the object.
	uploadID := newResponse.UploadID

	// content for the part to be uploaded.
	buffer1 := bytes.NewReader([]byte("hello world"))
	// HTTP request for the part to be uploaded.
	request, err = newTestSignedRequest(http.MethodPut, getPartUploadURL(s.endPoint, bucketName, objectName, uploadID, "1"),
