Reverse drag-and-drop

I just thought this morning it would be handy dealing with file structures with hundreds of projects to be able to drag-and-drop from Rhino on to a Windows Explorer window to save or export. How you would save OR export I have no idea, I’m just like, geez why do I have to navigate in the export folder picker to the folder I have open just right here?

It would also help, I think, at least in my case if on opening a file ALL the default folder locations were set to the folder the file is in instead of the last one used.
