Open the original- What it measures
- The page lists the MP4 video file and the M4A audio-only file that Zoom creates when a meeting is recorded to a computer, with their default names and the default folder on Windows and Mac.
- What it does not show
- The page is a university help article, not Zoom's own. One other university page gives a different default name, audio plus a number, so check the file name on your own computer.
