Not exactly; it's not possible with Win32 to do that.

What they do instead is
1. try to delete the file. If that fails for sharing
   violation, try 2.
2. move the file to the recycle bin, and set the
   "delete" disposition flag on the file, this will
   cause it to be removed from the recycle bin when
   the last handle is closed.
