Rapidshare itself does not offer a comfortable way to mange the files that have been uploaded to the file hoster. Rapidshare Manager on the other hand is providing an alternative solution. It’s only working with Rapidshare Premium Accounts and the Rapidshare Password and Username have to be entered during login to be able to access the files that have been uploaded.
The software is in early beta currently which becomes obvious during login because the login window was kinda messed up. The files that have been uploaded using the Rapidshare Premium Account are listed after logging in.
The files can be sorted in various ways like file name, size or last download. One nice feature is the ability to delete multiple files at once.
Several additional useful features are information about the Rapidshare account, exporting Rapidshare Links from selected files and IMDB support.
