If you run the network scanner from a USB drive or a removable drive, it's stored in a XML file in the same folder. If you run it normally from a hard disk drive, it's stored in the registry in HKEY_CURRENT_USER\Software\SoftPerfect\Network Scanner\Common in the Ranges parameter.
But if you would ever run out of inspiration for new features.....
- The ability to save a range + description in a favourites list like in IE
- The ability to export/import a txt/csv with ranges + descriptions
We'll make it favourites like it's made in IE, thanks for the suggestion! By the way, the network scanner supports multiple scanning profiles, so you can define multiple configuration files with the ranges needed.
