| - | WinSCP drag&drop shell extension is extension of the operation system (or rather Windows Explorer). It allows you to drag files from WinSCP directly to any folder (Explorer window). Without it WinSCP needs to download the files first to temporary directory and only after that Explorer transfers the files to their destination. While this happens transparently, it has several drawbacks. | + | WinSCP drag&drop shell extension is extension of the operation system (or rather Windows Explorer).

| - | To allow direct drag&drop downloads, the shell extension was developed. It misuses Windows Explorer CopyHook's. [[&url(mscopyhook)|CopyHook]] is 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 Explorer and transfers your actual selection to now-known destination. | + | To allow direct drag&drop downloads, the shell extension was developed.

| This on the other hand explains why with the extension you cannot drag files to any other application except for the Windows Explorer. No other application would call the CopyHook. | This on the other hand explains why with the extension you cannot drag files to any other application except for the Windows Explorer.
