@ Paul: I see that you haven't gone to the Belkin website. It explains what the Belkin Storage Manager is and what this software does. The Belkin website also explains how to use your external USB harddrive that is connected to the Belkin N+ Router without downloading the software. If you have the Belkin N+ Router with the USB port for an external harddrive, this is great software to use. I always use it. I just upgraded to Windows 7 and I am too lazy to find the install disk and find it to be easier to just download it from the internet.
