Use the well-known Windows drag-and-drop feature to transfer files and directories.
Make sure drag-and-drop is enabled in the Preferences dialog box. From the Options menu in the main window, choose Preferences > Advanced. Check the Enable drag-and-drop for directories box.
This enables you to:
Drag files and directories from the left (local) part of the main window to the right (remote).
Drag files and directories from your desktop or any other window to the server.
Right-click a remote file to open the pop-up menu.
