A cite from the MSDN article
Handling Shell Data Transfer Scenarios[

Quote:
Normally, a drop source has no way of knowing which folder its data object has been dropped on.
This cite is from the "Dropping Files on the Recycle Bin" section which defines the only exception when dropping on the Recycle Bin virtual folder where the Explorer creates a
CFSTR_TARGETCLSID
object that can be read by the drag source.
