return err
	} // Assert: dir does not exist

	// create the dir
	return fs.MkdirAll(path, defaultPerm)
}

// WriteTempDir creates a temporary dir at `path`, writes `files` into it, and fsyncs all the files
// The keys of `files` represent file names. These names must not:
// - be empty
// - be a path that contains more than the base name of a file (e.g. foo/bar is invalid, as is /bar)
// - match `.` or `..` exactly

# Static Files

You can serve static files automatically from a directory using `StaticFiles`.

## Use `StaticFiles`

* Import `StaticFiles`.
* "Mount" a `StaticFiles()` instance in a specific path.

```Python hl_lines="2  6"
{!../../../docs_src/static_files/tutorial001.py!}
```

!!! note "Technical Details"
    You could also use `from starlette.staticfiles import StaticFiles`.

{!../../../docs_src/static_files/tutorial001.py!}
```

!!! note "기술적 세부사항"
    `from starlette.staticfiles import StaticFiles` 를 사용할 수도 있습니다.

    **FastAPI**는 단지 개발자인, 당신에게 편의를 제공하기 위해 `fastapi.static files` 와 동일한 `starlett.static files`를 제공합니다. 하지만 사실 이것은 Starlett에서 직접 온 것입니다.

### "마운팅" 이란

"마운팅"은 특정 경로에 완전히 "독립적인" 애플리케이션을 추가하는 것을 의미하는데, 그 후 모든 하위 경로에 대해서도 적용됩니다.

# Request Forms and Files

You can define files and form fields at the same time using `File` and `Form`.

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

    E.g. `pip install python-multipart`.

## Import `File` and `Form`

=== "Python 3.9+"

    ```Python hl_lines="3"

			filenames <- filename
			nfiles++
		}
		return nil
	}

	// test Go files provided via -files, if any
	if *files != "" {
		for _, filename := range strings.Split(*files, ",") {
			fi, err := os.Stat(filename)
			handleFile(filename, fs.FileInfoToDirEntry(fi), err)
		}
		return // ignore files under -root
	}

	// otherwise, test all Go files under *root
	goroot := *root
