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:

    /** 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
    protected FileConfigService fileConfigService;

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