How to access my pc from school

HI….
Does any one know how to access my pc from school so that i could download some files from my hard drive. A lot of people say create a FTP server but i think that after i create the server already i will need to upload my files to the serverthen i go to school and download at school the files. And this is not what i really need. I need help in creating a network that wherever i need to download anything from my home pc i can do it at school..
Any comments pls email me at fsunglim@yahoo.com.sg
Thanxs!!!!!!!!!
