También puedes usar `File()` con `UploadFile`, por ejemplo, para establecer metadatos adicionales:

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

## Subidas de Múltiples Archivos { #multiple-file-uploads }

Es posible subir varios archivos al mismo tiempo.

Estarían asociados al mismo "campo de formulario" enviado usando "form data".

Para usar eso, declara una lista de `bytes` o `UploadFile`:

#       export TF_ANY_TARGETS="quoted list of targets, like on the command line"
#       export TF_ANY_MODE="test" or "build" or "run" (default: "test")
#       ./any.sh
#
# 2. RUN ANY OTHER SCRIPT AND ENV WITH NO SIDE EFFECTS (NO UPLOADS)
#    To use:
#       export TFCI=ci/official/envs/env_goes_here
#       export TF_ANY_SCRIPT=ci/official/wheel.sh
#       ./any.sh
#
# 3. DO THE SAME WITH A LOCAL CACHE OR RBE:

level, unlike other object storage vendors. This allows applications to choose different storage class by setting `x-amz-storage-class=STANDARD/REDUCED_REDUNDANCY` for each object uploads so effectively utilizing the capacity of the cluster. Additionally these can also be enforced using IAM policies to make sure the client uploads with correct HTTP headers.

- MinIO also supports expansion of existing clusters in server pools. Each pool is a self contained entity with same SLA's (read/write quorum)...
