Replace "rapidshare.de" with "rapidsnare.de" and after just 4 requests (from different IPs) they mirror the file and you can download without waiting. Big files are splitted in ~50MB parts with a bat file to join them after download.
I think are Download managers are supported
The user interface is a bit strange, you need to click the file link to see the actual download link for each file. OR you can just open all links in new windows and grab them from there.
If you request big files, make SURE you first test if they are still busy splitting them, by right-clicking on the link and using "save target to". If you get a server not found error, just wait a few minutes or reload the page and everything works fine.
I suggest u use an ad blocker and an image blocker on this site.
Here is an example
