Usually file hosts don't list the files they hosts. They don't even have a search function.

It's the uploaders who upload their files to these hosts who publish the links to these files on other websites, mostly blog sites. It's these links that you'll find on the web by searching (using a web search engine) for your media.

Most hosts allow you to download these files for free, some offer a free membership but these registrations often don't offer any advantages when compared to anonymous downloads.

In order to be profitable these file hosts also offer paying subscriptions, so-called premium accounts. These should offer the best conditions to download files from these hosts.

If you mean the German in the first post of the captcha thread, then don't worry. German is a very difficult language but all necessary information has been translated to English.
