FileFury is a free, open-source Windows program which allows its users to share files over the Internet. Employing an Explorer-like interface, users can choose sharing properties for the directories on their computers; once shared, a directory can be surfed or searched from any other computer, and the files therein can be downloaded. One essential feature of FileFury is its search feature; a search will instantly crawl hundreds of thousands of online users, trying to match the search criteria you provide. Searches can cover file names, or MP3 tag information; and since the searches are executed in real-time, the results are always valid. Security is also a key concern for FileFury; only explicitly-shared directories and their contents can be viewed and copied.
