Initially the Ajax Directory Manager was developed for design company Duarte Design but in the process Chris Iufer decided to name the project Relay and release the code to the public as open source.

Relay is regarded as the better way of managing site files for blogs or personal homepages and to transfer files between web- based designers and their clients. The Ajax powered file manager provides easy and intuitive file management via an internet connection. Functionalities which are included are sliding menus and live previewing of images and PDF files.

The code can be downloaded at http://ecosmear.com/relay/. Online one can also get the live demo and community wiki.
