How to set up a home FTP server

A home FTP server is useful to anyone who wants to save and retrieve files on their computer from anywhere. Ever forget a Word document on your home desktop that you really need at work? Ever download a PDF that explains how to fix something at work and you realize too late you left it at home that morning? If you have a personal FTP server, and you can reach your computer from any place on earth, your files will never be captive on your hard drive at home again
