| To allow direct drag&drop downloads, the shell extension was developed. It misuses Windows Explorer CopyHook's. [[msdn>bb776048|CopyHook]] is a COM object (DLL library) that is called by Windows Explorer whenever directory (not file) is transferred within file system. When you drag anything from WinSCP, it creates empty dummy folder in temporary directory and pretends that you as user drag that directory. Once your drop it to Windows Explorer, it calls the CopyHook's (including the WinSCP shell extension), telling it what and where was dragged. This way WinSCP knows the actual destination. It cancels the drag&drop operation, so the dummy directory is not copied by Windows Explorer and transfers your actual selection to now-known destination. | To allow direct drag&drop downloads, the shell extension was developed.
