WISE-FTP allows you to manage existing sites in directories with meaningful names. This simplifies site management (especially if the number of sites increases).
It may be helpful to arrange sites in directories according to topics, e. g. one directory for download sites offering free games, one for software updates, etc.
From the Tools menu, open Site Manager. Like in Windows Explorer, you may use drag-and drop. Move mouse pointer over desired object, and drag it into desired directory with left mouse button pressed.
