The RM extension stands for “Real Media”. It is basically used by Real Player software. This software streams videos over the Internet that visitors can view directly. Files with this extension are often used together with RealAudio and RealVideo files. You can download the video from Real Media in RM format to watch later. You will need a file called “Real Alternative Codec Pack” that allows different video players to use RM. RM can also be used to listen to music on some of the music players. This format is owned by a company called RealNetworks Inc. It also allows users to watch different streaming videos on the Internet.

The SWF extension is used by multimedia files that need the Adobe Flash plug-in to play. These files are used by many applications, such as video embeds on total websites. They can create a rich visual experience. The files are typically embedded or included when the site loads, and most users don’t need to download them individually. They are also known as Flash. The company that owns the extension (Macromedia) called it SWF, which stands for “ShortWave Flash”, but later changed it to “Small Web Format”. Many sites use Flash files for many different reasons. Some sites use it to add visual appeal. Most Internet users have Flash installed. It is one of the most widely used Internet technologies.

Compared to RM, Flash is a more popular method of adding animation and interactivity to web pages. It is also most commonly used to create advertisements, animations, and other web page components and to develop Internet applications.
