What a .avi file is

AVI was introduced with Video for Windows and is a simple container that can hold nearly any codec. It has no proper support for modern features like variable frame rate, subtitles or files over 4 GB without extensions, which is why it has been replaced by MP4 and MKV. Old AVI files sometimes use codecs Windows no longer ships, so VLC — which carries its own decoders — is the reliable way to play one.

Converting it

A .avi file is commonly converted to .mp4, .mkv, .mov, .webm or .gif. It is a binary format, so a text editor will show unreadable characters rather than its contents.
