HDR conversion inside C4D

I have had some ooooold HDR probes sitting somewhere on my harddrive - one day I would buy HDR Studio and convert them...

But actually C4D can convert probes and crosses (HC and VC) in the image viewer to the C4D Longitude/Latitude format for skies. It does it automatically, you open the file and - le voila. A great little gem hidden away!
