PTP2.0 + Nikon + Return Image Filename

[TravisH84]

I saw that it was mentioned in some of the Demo's that the PTP examples can capture an image and through the serial terminal return a filename of the image captured.

I had a look and have not been able to find this, is it possible to present an example that does a capture and also returns the captured filename? (I use Nikon, but a generic example would be great).
