I currently don't use samba, but yes, it was made to share directories, files and printers. I would download webmin (webmin.com) to set it up for a quicker and easier way to manage it. Or if you feel adventurous, you could buy a book from oreilly, "using samba" and write your own conf file for sharing. (

The only one that could set this up is your admin at your school unless you figured out his root password
Also, if you are a student, shouldn't you be learning instead of playing games and listing to music, and if you are the admin, shame on you hehe
