When you upgrade your old PC, what do you do with the old system? Give it to someone else, pass it on for recycling or simply leave it in a cupboard thinking you'll do something useful with it, later. Probably the latter. If you have a fast broadband connection, whether you have a static IP address or not, there's no reason why you couldn't dust down your old PC and then configure it as a file or FTP server to provide files, downloads and more to friends and family. The only snag is, you need an easily-configured FTP server.
Quick n Easy FTP Server 3.2 is a server aimed at the novice user (there's an even more basic Lite edition, with limited features) that will enable you to install on your system as a service, so that if your PC goes down, the server will start up automatically when you boot your computer.
