Where is the file *.NavData coming from?

Question

I have a Java EE 7 application with FlowSoped objects and use NetBeans.

Git shows me a new file: myFlowName-flow.NavData

Where does it come from? What is this?

<?xml version="1.0" encoding="UTF-8"?>
<Scene Scope="Project" version="2">
    <Scope Scope="Faces Configuration Only"/>
    <Scope Scope="Project"/>
    <Scope Scope="All Faces Configurations"/>
</Scene>

As illustrated by this commit, it is a generated file.

A typical JSF project should ignore it, as in this .gitignore
