With an eye towards enhanced downloading of files from social networking sites, Orbit Downloader is well worth a look. The application uses a fairly basic interface, and it's easy to use, as visitors can just right-click a video or photo and select the "Download" function from their menu to complete the action. Another useful feature is the one-click button that allows users to download multiple files from any given site. This version is compatible with computers running Windows 2000, XP, 2003, and Vista.
