## Importar `File` { #import-file }

Importa `File` y `UploadFile` desde `fastapi`:

{* ../../docs_src/request_files/tutorial001_an_py39.py hl[3] *}

## Definir Parámetros `File` { #define-file-parameters }

Crea parámetros de archivo de la misma manera que lo harías para `Body` o `Form`:

{* ../../docs_src/request_files/tutorial001_an_py39.py hl[9] *}

/// info | Información

`File` es una clase que hereda directamente de `Form`.

Such objects do not produce efficient [`LZ compression`](https://en.wikipedia.org/wiki/LZ77_and_LZ78)
which is a fitness factor for a lossless data compression.

Pre-compressed input typically compresses in excess of 2GiB/s per core,
so performance impact should be minimal even if precompressed data is re-compressed.
Decompressing incompressible data has no significant performance impact.
