This software uses NBR (Network-Based Recording) to save and download the video recording of a meeting that has taken place on the internet. Contrary to WRF files, ARF files contain the downloaded recording of an online meeting. WRF is the extension of recorded sessions in a video format that have been recorded by a user themselves.
