This software is some kind of portable office on an USB-key, which would give the ability to start different applications from one central point, without having to install them first. It also has the ability to scan computers for viruses and spyware. All utilities used are freeware.
The use is very simple. The first time you have to make sure you have an internet connection, because the application you want to start, will have to be downloaded first. You can start the application, just by clicking on the icon. While moving the mouse cursor over the icon, you will also see a short description of each program.
The program has an PortOff.ini file. This file contains the web links to the download sites of the applications. If an internet address or filename should change, you can adjust this ini-file, and save the changes.
