Stick them on a CDRW and carry it in your pocket. Unless you really don't care if anybody in the world might see them, then you could stick them on the webserver. But surely you must have heard about the many occasions when information leaked out of a webserver. Would you be upset if that happened to your information? Does anybody else have access to your webserver? If it's a shared server, then it will be quite difficult to stop other users from being able to see your files.

Of course, you could try encrypting the files first... But if it was my "special personal files", I'd put them on a CDRW, or on a laptop computer.
