DHX Files commander

I’m not sure where to ask this question since the “Uncategorized discussions” is locked. In the Samples page there is a Files Commander that I am very interested in but have been unable to find any documentation or reference on it. Is there any documentation? Are there and additional files? Is this even available?

It is just a demo, not special component - there is no special documentation about it.
