RB The .rb extension is used for many formats which include definition files based on the Fuzzy rule, eBook files of the Rocket Edition, class files of Ruby on Rails, project files of REALbasic and the profile configuration files of Rosebud. Other versions of Ruby which are also called gems include Mongrel, Capistrano and Ruby on Rails.
FB2 The .fb2 filename extension refers to the open XML based eBook format known as FictionBook. The file format was developed by Dmitry Gribov with an initial release in 2004, quickly gaining popularity in Russia. The format is open which in this context means it has no compatibility with digital rights management technologies. The structure of the format splits the contents of the data into three sections; title information, XML document information, and finally information about the paper edition which is optional.
