Upload and transfer scripts

Someone who knows about a script like rapidshare / megaupload which is based on php and mysql, that I can have on my own server?

For easy upload and transfer management.

 

This one ?

Thank you. It looks very good
If anyone knows of any other script, I am very interested. As long as it's free .

 

I'm using this one:
