What is this for?

Type the exact name of a file or some of the name:

Eg. You want to download Photoshop but you dont want to have to register on the Adobe site to get it. You would type AdobePS7Tryout.exe and then select one of the results and download the file.

Eg. You want to download some MP3s by Paul Okenfold. Type paul oakenfold and then browse the results and you may even find some other tracks you like too!

Eg. You want to download a BBC Top Gear video of a Ferrari. Type "top gear" Ferrari and then select one of the results and download the video.

Eg. You want to download MP3s. Type mp3 and then browse the pages and pages of MP3s for something you like.

It works because most of the webservers on the internet use Apache which always titles pages in the same way, index of /whatever/stuff when serving the contents of a directory.
