  • Proprietary format with poor cross-platform compatibility
  • Not supported on iOS, many Android players, or web browsers without plugins
  • Declining usage and relevance in modern video workflows

Common Uses

  • Legacy Windows video libraries and media collections
  • DRM-protected video content from older platforms
  • Windows-based screen recordings and presentations
