file name location in the UI

dave_5039306

I just bought the steam and smoke collection. I am using Studio to review the files. I drag the file in to the viewport, and once I do that, I can no longer find the actual file name for each vdb. I checked Info and it just has a generic name with a number after it like "VDB Steam n smoke (3)" but the actual names are more like "SSMP Volume Still Small 01 26" or something like that. 

How to I find the file name once I've dragged it in to my scene? I want to know that so that I can use my combination of stuff in Cinema 4D but I now have no idea which files are in my viewport/scene.

Probably a simple thing but nothing I'm doing seems to be callind up the actual name.

UI screenshot attached.

Thanks

Dave
