What is drag and drop action?
The action of picking an object or chunk of text, moving it (dragging), and then dropping it in a different area is known as drag-and-drop. To drag and drop an object, such as an icon, for example, you must first move your mouse cursor over it. Then, while holding down the left mouse button, drag the object to the desired spot and release the mouse button to place it.
Dragging and dropping an object or file moves it to the new location; it does not make a copy.
