* You don't have to use `File()` in the default value of the parameter.
* It uses a "spooled" file:
    * A file stored in memory up to a maximum size limit, and after passing this limit it will be stored in disk.
* This means that it will work well for large files like images, videos, large binaries, etc. without consuming all the memory.
* You can get metadata from the uploaded file.

Mit `File` können sie vom Client hochzuladende Dateien definieren.

/// info

Um hochgeladene Dateien zu empfangen, installieren Sie zuerst <a href="https://andrew-d.github.io/python-multipart/" class="external-link" target="_blank">`python-multipart`</a>.

Z. B. `pip install python-multipart`.

Das, weil hochgeladene Dateien als „Formulardaten“ gesendet werden.

///

## `File` importieren

```

////

/// info | "Дополнительная информация"

`File` - это класс, который наследуется непосредственно от `Form`.

Но помните, что когда вы импортируете `Query`, `Path`, `File` и другие из `fastapi`, на самом деле это функции, которые возвращают специальные классы.
