The DASH file format was designed to store digital video content in different bit rate levels. Also called DASHlane files, a .dash video file is generated while digital video content is streamed on the Web.Used by online video repositories like Netflix and Youtube among others, the DASH file format is similar to the MP4 video format. DASH refers to Dynamic Adaptive Stream over HTTP. The ability of the DASH file format to store digital video content in multiple bit rate levels enables the online video player to stream the video based on the viewer's bandwidth and CPU resources. This means the online video player can adjust the bit rate of the digital video content that's stored in a .dash file during playback.These DASH files can be opened and viewed through the DASHlane program. Other applications that can be used to open and view the digital video content in a .dash file include VLC Media Player and RealPlayer.
