If you download the new opera webbrowser fromthen you can share files on the internet with everybody, it has a build in server, that server caches via you need to register and set a password. You then get a web address, I got this: You can make any folder public, and also protect it with a password if you want. So in fact it creates your own webserver!
Opera is available for almost every operating system now.
I can only recommend this browser.
This opera.unite feature can do a lot more too, it is sort of a solution for those of us who want to share pictures and diagrams.
Opera must be running for the files to be accessible though.
