- Description
- An ASF file is a media file stored in the Advanced Systems Format (ASF), a proprietary video and audio container format. It contains audio and video data and optional metadata, such as title, author, and copyright bibliographic data. ASF files are developed by Microsoft primarily for streaming media.
- An RMVB file is a Real Media video file compressed using a variable bit rate, which is optimized for the content of the video. It is a newer variation of the standard Real Media (.RM) file format that allows for more efficient compression.
