Copy or Move?

As you know, you can use the drag and drop feature to copy or move files and folder. If you press CTRL key when you drag and drop an object, that means you are doing Copy operation. Meanwhile, if you press SHIFT key when you drag and drop an object that means you are doing Move operation. However, these rules are not valid anymore when you work with two or more drives. If you drag and drop an object from one drive to another drive, that means you are doing the Copy operation whether you are pressing the CTRL & SHIFT key or not.

Use the mouse pointer as your guide. If the mouse pointer has a plus sign that means you are now doing the Copy operations. Meanwhile if the mouse pointer has nothing inside it that means you are doing the Move operations.
