To start recording there is only need for a file name. Using `\`, `/` or `:` characters in the file name will define it as an absolute path. If no path is detailed, the file will be saved in `CarlaUE4/Saved`. To start recording there is only need for a file name.

By default, the recorder is set to store only the necessary information to play the simulation back. In order to save all the information previously mentioned, the argument `additional_data` has to be configured when starting the recording.
```py
