note that groupByKey() provides an expensive solution,   but combineByKey() and reduceByKey() will give a better   scale-out performance

Have you noticed the cool ghost image that Windows Explorer produces when you start dragging files/folders from it? Well, I wanted to implement this in a C# project when dragging files between it and Windows Explorer. After a lot of Googling, I found out that there are three directions to start working on, as follows: Using a "custom" cursor created from a MemoryStream initialized from an Image, as shown in this article. Using the ImageList_BeginDrag and related APIs, as shown in this article: Dragging tree nodes in C#. Using the IDragSourceHelper and IDropTargetHelper interfaces.
