What is a WMV file?
WMV is Microsoft's Windows Media video format, stored in the ASF container. It was common for Windows Movie Maker exports and early web video in the 2000s.
WMV is mainly used for older Windows Movie Maker projects and legacy corporate videos. It plays on Windows Media Player and Movies & TV on Windows, and VLC; Macs, iPhones and browsers do not play WMV natively.
