What is a AVI File?

AVI (Audio Video Interleave) is a multimedia container format introduced by Microsoft in 1992 as part of its Video for Windows technology. Once the dominant video format, AVI can contain both audio and video data allowing synchronous playback. While still widely used for legacy content, AVI's lack of modern compression support makes it significantly larger than contemporary formats like MP4.
