AVI, standing for Audio Video Interleave, is developed in 1992 by Microsoft. It is the standard form for Windows. It uses less compression compared to many other video formats and thus takes relatively more storage. Usually, it takes about 2.5G to store a 1-minute video.

Just double-click the file. Your Windows will open it with the Windows Media Player by default. If you have set a 3rd party player as the default video viewer, Windows will employ it to open it instead. Mac users can use VLC, Kodi, and DivX Player to do this.
