There are several free "virtual hard drives" available. There used to be a lot more, but now.... there's just a few.
I'm not lucky enough to have a CD writer. My floppies often, over a period of time, become messed up.
So, once a month I upload my updated most important files to a virtual hard drive.
The one I'm using is http://www.storagevault.net
They offer 10mb free. For more they charge.
Good luck! Hope this helps.
