When an application implements the drag-drop feature, a user can select one or more files in Windows File Manager, drag them to an open application, and drop them there. The application receives a message it can use to retrieve the filenames and the coordinates of the point at which the files were dropped.
Following are the new drag-drop functions:
| Function | Description |
| DragAcceptFiles | Registers whether a window accepts dropped files. |
| DragFinish | Releases memory allocated for dropping files. |
| DragQueryFile | Retrieves the filename of a dropped file. |
| DragQueryPoint | Retrieves the cursor position when a file is dropped. |
The drag-drop feature depends on the dynamic-link library SHELL.DLL. This is a redistributable library.
