|Generally you create some sort of web page that has either a link to the file you wish to offer or some page with a listing of files. It can be a http, https or ftp link. |
The method you use to upload the web site is the same for the files. Good web creators allow you to fix all the links and upload the entire site by a click or two.
Most web servers that you rent online offer some web based way to access your space or a ftp server to access.
Hang up and live.
