# Working with the filesystem

If you need to create a file (e.g. creating XML feeds) or to work with the filesystem, you should use our `.saveOutput()` function.

```typescript
import { functions } from "@xomlo/xomlo-sdk";

functions.main(async () => {
    await functions.storage.saveOutput('test.txt', 'test');
});
```

Function .saveOutput() expects two parameters - the name of the created file and content. This example will store the `test.txt` file into the `./output` folder which will contain the following string: `test`.
