Core FTP Lite gives you FTP access to your site, allowing you to upload and download files, create /remove directories, and create/remove files, among other functions. Using the download set up by SVSU, you also have FTP access to your M: Drive through NetStorage and the CSIS server (for students of the CS and CIS programs).
When you first open Core FTP, you will be given a Site Manager dialog. This is where you will set up your site. Most of the fields have already been filled in for you, but you should make sure that things are set as needed.
If you haven't yet, create a new folder somewhere on your computer to be the home for your local copies of the files placed in your web space.
