2.5 drag and drop

[LiangTyan Fui]

I've managed to grab files dragging from Finder into MetaCard 2.5 by using
the newly implemented drag-and-drop. The dragData furnished with files and
path.

But how do I reverse the process? All I manage to do now is dropping some
text clipping into the Finder.
Let say I have objects in a stack, when user drag one of the objects out of
stack and drop it into the Finder, all I need is the path to the Finder
window and export the related files (it could be png graphic).

Anyone done that? On Windows too?
