* `seek(offset)`: Переміщується до позиції `offset` (`int`) у файлі.
    * Наприклад, `await myfile.seek(0)` поверне курсор на початок файлу.
    * This is especially useful if you run `await myfile.read()` once and then need to read the contents again. Це особливо корисно, якщо Ви виконуєте await `await myfile.read()` один раз, а потім потрібно знову прочитати вміст.
* `close()`: Закриває файл.

Pasar el `root_path` a `FastAPI` sería el equivalente a pasar la opción de línea de comandos `--root-path` a Uvicorn o Hypercorn.

### Acerca de `root_path`

Ten en cuenta que el servidor (Uvicorn) no usará ese `root_path` para nada, a excepción de pasárselo a la app.

 * in the case of Android, the current app. If that is not possible (as is the case under the very
 * old Android Ice Cream Sandwich release), then this class throws an exception instead of creating
 * a file or directory that would be more accessible.
