return FileUtil.readFile("d:\\tmp\\file.csv");
```

#### Example: Retrieve data from API and return as File

```typescript
// Make an HTTP request to get exchange rates from the specified API
var request = HttpUtil.get("https://boi.org.il/PublicApi/GetExchangeRates");

// Parse the response body as JSON
var jsonContent = JsonUtil.parse(request.asString().getBody());

// Convert the exchange rates to a JSON string
var exchanges = JsonUtil.stringify(jsonContent.exchangeRates);

// Create a temporary file and write the exchange rates JSON to it
var tempFile = FileUtil.createTempFile("tmp.json", exchanges);

// Return the path to the created temporary file
return tempFile;
```
