This program may be used to monitor the Internet traffic on a computer. It shows how many bytes were uploaded/downloaded. It might be useful to avoid extra charge if the Internet Service Provider sets a monthly traffic limit. In order to automatically start the program in background a shortcut may be added in StartUp menu. To start the program without user interface, the switch /s must be used. In this case only the icon in the taskbar's status area will be visible. The main window still can be displayed if user clicks on this icon. It can be configured to generate a log file and/or a .CSV file where mothly usage is logged.
