At the top of the Dataflow Modeler board, there is a **toolbar.**

The **New** button\
The New button unsurprisingly creates a new Model from scratch.

The **Save** button\
Never forget to save your Models! Click on the SAVE button and choose whether to save the Model as Draft or, once you have saved it at least once, promote it to Master.&#x20;

The **Reset** button\
You can restore the model to its last saved state. This is useful if you need to discard the most recent changes.&#x20;

The **Export** button\
To export a model, click the export button and it will be downloaded as .txt file on your local disk.

The **Import** button\
To import a model, click the import button and browse your local drive to locate the model (it must be a .txt file) and upload it. The model will be imported and shown on the **Dataflow Modeler** page for processing.

{% hint style="warning" %}
It is recommended to import only models previously exported by Primeur Data Watcher.
{% endhint %}
