I was wondering if there are some applications for downloading files from some popular hosting websites, automating the procedure of waiting and fetching links and downloading files, once we give the applications the links?

Examples of such websites are 

* Rapidshare,
* Uploading,
* Megaupload,
* Filesonic,
* Fileserver,
* Hotfiles,
* Depositefiles,
* iFile.

But the applications are not necessarily applicable to all of them.

Thanks and regards!

ADDED:

I just tried slimrat. It failed to download files from rapidshare. Can it be because the website of rapidshare has changed recently and the parsing functionality for their website by slimrat is not up-to-date yet.
