Relay: An AJAX Directory Manager…
“Are you fed up with that lame old directory manager your hosting company provided you with for you website or blog? If you are already familiar with windows or mac file browsers, why should you have to change the way you work for the web? Try Relay for a change.”
Relay, a directory manager and file uploader, has been released as open source. I haven’t had a look at the code yet, or attempted to install it myself, but the demo looks good. At the very least, it could be a good base to build upon for other projects.
