Ever since Microsoft introduced mice into their operating systems (something done earlier by other vendors such as Apple and pioneered by the Xeros PARC - Palo Alto Research Center - mythical design team) we could drag-and-drop items from one spot of the graphical user interface (or GUI) to a different spot. I will not go into the basics of drag-and-drop as I assume that if you’re advanced enough to read this article then you’ve mastered these actions as a reasonable level, but instead I will remind you of some of the advanced techniques in dragging-and-dropping. These will allow you to have more control over items when you're dragging-and-dropping items.
Since many users deal with more than just typing documents and replying to emails, most of us will have had a chance to drag-and-drop a file or folder from, for instance, a USB flash disk to their My Documents folder. It is important for us to be able to determine what will happen when you drag-and-drop an item from one location in the GUI to another, and that is before you perform the actual dropping.
Now here is where the challenge hides: Drag-and-drop functions are handled differently in various situations. Based on the drag-and-drop scenario the end result changes, and unless you know what will be the outcome of your drag-and-drop action, you might find yourself without the necessary files in the middle of an important presentation. Therefore, in order to achieve the required result you will sometimes need to change your default behavior. Here is a list of the rules that Windows works by when determining how dropped files are handled:
