The drop here refers to 'drag and drop', a common activity in GUI-based operating systems, where the icon of a file or program is dragged (by clicking on it and then drag-move the mouse while keeping the mouse button down) to a designated area and then releasing the mouse button. It is usually employed to use a file/program as the input to another application.

نقشک is the Persian equivalent of "icon" suggested by the Iranian Academy of Persian Language and Literature.
