WMV (Windows Media Video) is Microsoft’s video format, once common for Windows clips and PowerPoint. It keeps files small but plays poorly outside Windows - Macs, phones and web browsers often can’t open it, so MP4 is the safer choice for sharing.
WMV plays in Windows Media Player and VLC; on Mac, phones or the web, convert it to MP4 first.
M4A is an audio format that usually holds AAC-encoded sound in an MP4 container. It is Apple’s standard for music downloads and voice memos, offering great quality at small sizes and playing natively across the Apple ecosystem.
M4A plays in Apple Music/iTunes, QuickTime, VLC and most modern media players; on older devices, convert it to MP3.
