dos commands you may need:
cd (change directory) e.g. cd myFolder will move to that directory assuming it exists in the current directory
cd.. go up a level
copy (follow natalia's instructions)
dir/w lets you see what's in a directory
[aFolder] denotes a folder
hope that helps, and at least you backed up all your important stuff, I didnt and my 40 gig drive died. But then I found an ancient backup so it aint all bad
And as far as logging in you can log in anywhere on any ISP I switch between uni and home all the time. You will just get a new cookie on the new machine.
good luck and post again if you need help with the dos stuff.
