Never fear, Petey is here!
If you're asking what I think you're asking, you want a web-based file management system that you can upload and download to/from anywhere on the Internet.
http://invisionfilemanager.com is a good one. I use it for a webpage that I set up for my junior class.
If that's what you want, and you want any help configuring it, let me know.
