The WMA file format was created by Microsoft and is a proprietary file format. The audio in WMA files are compressed similar to MP3 and OGG files. However, since WMA files are a proprietary format, they aren’t fully supported by all multimedia devices. You can sometimes find WMA and WMV (Microsoft’s Video equivalent) files using another one of Microsoft’s proprietary digital audio and video container format known as ASF. However, WMA and WMV files are more common. Microsoft Windows Media Player 9 was the last version of the Windows Media Player developed for Mac OS X. However, Mac users can use Flip4Mac WMV (also known as Microsoft Windows Media Components for QuickTime) to play WMA files. Windows Media video files use a .WMV extension.
