The follow article explains how to upload your website to servers using FTP (File Transfer Protocal) through a windows explorer. The basic idea is to first establish a connection with server and your computer and then upload the files. This will transfer your website to servers so that others can view your site on the internet.
Once you successfully login you will see a listing of the files in your website on server.
You can now drag files from your local computer into this folder to upload files to server or drag files from this folder to your local computer to download files off your website.
