You should use a program called WinSCP. You can download it here: http://winscp.net/eng/download.phpI am using *nix at home:
There will most likely be an scp package installed on your machine (if not refer to the manual of whatever ditribution you're using to install scp). In order to copy a file to lore you need to type:scp <filename> <login>@lore.cs.purdue.edu:<path/filename>
