AVI is a file format created by Microsoft. It stores video data that may be encoded in a variety of codecs and typically uses less compression than similar formats such as MPEG and MOV. WMV, in its turn, is a video file based on the Microsoft Advanced Systems Format (ASF) container format. It uses Windows Media compression technology.
Both formats are popular among users and can easily be opened with standard programs like Windows Media Player, Media Player Classic, etc. However, sometimes users face a need to combine two AVI files into one WMV. For this purpose, we suggest you try Total Movie Converter developed by CoolUtils.
