Filetopia is a free, multi-platform peer-to-peer file sharing client, and networking tool that allows users to share files, use chat, and send instant messages. Users can share files in public chat rooms or privately with contacts (by searching or using shared files list). As it is not a centralized system, users must connect to a network made of multiple servers in order to find each other. However all the file transfers, secure chat, etc. are conducted on a peer-to-peer basis. By default Filetopia is not an anonymous peer to peer network: when sending or downloading files, IP addresses are not visible, but the software makes no attempt at keeping them anonymous. History Filetopia software development started in October 1998 and the first public beta was released in March 1999. In April 2012, development began on a project to completely rewrite the program in Java FX. This version was eventually released as Filetopia FX. The classic Filetopia software version (3.04d, 2002), is still (as of 2015) a small, but vibrant community of people sharing a wealth of data. In 2003, Filetopia v3.04 was reviewed in PC Magazine, and rated 3/5. In 2004, the author of Filetopia was interviewed on the web site Slyck.com. Filetopia FX (from 2015) This Filetopia FX version is more focused in hosting Online Communities than in file sharing, disallowing global-wide file searching and encouraging meeting new people. It is a complete rewrite using modern technologies which improves over the Classic version in the following areas: The maximum file size limit of 2 GB has been removed. Graphic chat was vastly improved. There are configurable chat presets, hundreds of emoticons and users have the ability to add new ones and capture those they like from the chat. Users also have the ability to post images and HTML fragments (which are filtered for security purposes). Lastly, improvements have been made on all existing chat features. Messages now use the same technology behind the chat and can take advantage of all its graphic features. Room Walls are now graphic and have comments, votes, moderation and are able to notify admins and subscribers of changes. The Log is now a graphic one, that is kept encrypted for security purposes. with a powerful search function. In addition, logs now have a powerful search feature to enable users to quickly find what they are looking for. File sharing protocols were completely rewritten. They
