Although there are many leeching applications available out there, and somebody even selling their own scripts. As a Web developer, I think it's good to come out something light and sharing this with everyone. Therefore, I have wrote a small PHP application to make the migration tasks in RapidShare easier.
It's working with both free and premium accounts. However, I'm not really try out the premium download yet as I do not have a premium account on hand.
Feel free to try it out and feedback to me.Download: http://seikan.me/files/rs2rs1.0.zip (6.26 kb)
