SWF is a flash animation file format created as a flash development application. In particular, for Adobe Flash. Users of the global network had to watch advertising animations when the picture “comes to life” and changes, you just have to point the arrow of the manipulator on it. This format has gained great popularity in the global network, because it uses videos and banners, as well as special flash-games. Such files usually contain text or animation, in which there are inserts of vector, bitmap images, audio tracks, as well as scripts in the Action Script language. This extension belongs to the category of video files. This format was created in 1995 by the Future Wave Software group of Americans. At that time, Future Splash Animator had the SPL extension. A year has passed. Macromedia bought the extension rights and gave the application a new name - Macromedia Flash. And then, in 2005, this company was acquired by Adobe. It was then that the beginning of the modern history of this expansion was laid.

RM is a video file format developed by RealNetworks. It uses the RealPlayer player, that is, a program for streaming audio and video files. The format contains audio and video data or links to streaming, which can be played back as it downloads. The RealMedia Player program was in great demand when they connected to the Internet using a modem, and when there was practically no broadband access to the global network. The large compression ratio of the format provided the opportunity to carry out online transmission of video and audio data. The quality of the output file, as a rule, was low. Today, such files are often used in order to broadcast Internet radio and Internet video. In the .RM format, music and video are found on the global network or on Western cable channels, on Internet radio stations. Support for this format is carried out by such mobile phones and smartphones as Nokia, Ericsson, Sony, iPhone, as well as mobile devices that operate on the Google Android operating system. Files with the extension .RM are compressed using proprietary codecs RealVideo and RealAudio. Individual Real Media files can be played using a VLC media player that partially supports RM files.
