## Importar `File`

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

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

## Definir Parámetros `File`

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`.

The main limitation is that to update or delete content of a file inside a ZIP file the entire ZIP file must be replaced.

        for (SmbFile file : files) {
            try {
                entry.updateChild(file.getName(), file.length(), file.lastModified(), file.isDirectory(), file.getAttributes(),
                        file.createTime(), file.lastAccess());
            } catch (Exception e) {
                log.debug("Error updating cache entry for {}: {}", file.getName(), e.getMessage());
            }
        }

        }
        testLeaseKey = new Smb2LeaseKey();
    }

    @Test
    public void testHandleInfoCreation() {
        HandleInfo info = new HandleInfo("/test/file.txt", testGuid, testFileId, HandleType.DURABLE_V2, 120000, testLeaseKey);

        assertEquals("/test/file.txt", info.getPath());
        assertEquals(testGuid, info.getCreateGuid());
        assertArrayEquals(testFileId, info.getFileId());

And your **FastAPI** application might also be composed of several files/modules, etc.

### **FastAPI** app file { #fastapi-app-file }

Let's say you have a file structure as described in [Bigger Applications](bigger-applications.md){.internal-link target=_blank}:

```
.
├── app
│   ├── __init__.py
│   └── main.py
```

In the file `main.py` you have your **FastAPI** app:

		n := 1
		var base, ext string
		base = *privKeyPath
		if idx := strings.LastIndexByte(base, '.'); idx != -1 {
			ext = base[idx:]
			base = base[:idx]
		}
		for {
			// Automatically read "file.ext", "file-2.ext", "file-3.ext"...
			fn := base + ext
			if n > 1 {
				fn = fmt.Sprintf("%s-%d%s", base, n, ext)
			}

			if b, err := os.ReadFile(fn); err == nil {
				privateKeys = append(privateKeys, b)

            } else {
                url = url.replaceFirst("file:/+", systemProperties.getProperty("file.protocol.firefox", "file://///"));
            }
            break;
        case CHROME:
            if (isLocalFile) {
                url = url.replaceFirst("file:/+", systemProperties.getProperty("file.protocol.winlocal.chrome", "file://"));
            } else {

    /** Service for file authentication operations. */
    @Resource
    private FileAuthenticationService fileAuthenticationService;

    /** Pager for file authentication list pagination. */
    @Resource
    private FileAuthPager fileAuthenticationPager;

    /** Service for file configuration operations. */
    @Resource
