By default, when you drag an item in File Explorer from one location to another, the behavior is not very consistent. When you drag and drop from one location to another within the same volume (partition), the item gets moved. If you drag and drop across locations on different drives, the item by default is copied. In this article, I would like to share with you a simple tip on how to reliably know what action will happen when you use drag and drop on selected items in File Explorer.
If you hold down the Ctrl key while dragging it with left click, the item will always be copied. If you hold down the Shift key, the item will always be moved. If you hold down the Alt key while dragging, Explorer will create a shortcut. You can customize this behavior with the Drag'n'Drop Editor app.
Instead of left click and drag, you can right click and drag because what action takes place is unambiguous if you use right-click.
Windows has the feature to display the drag action menu since Windows 95. Right clicking and dragging shows you a menu where you can choose what to do with the dragged items. If you have more apps installed like PerigeeCopy, their verbs will also appear in the context menu when you right click and drag.
That's it. This feature is little-used and not very popular because it isn't discoverable. Well, now you know.
