If your zoom meeting was recorded but does not show up in the Cloud Recordings tab, you may have saved the recording to your local computer.
For Windows users:
1. Open your Explorer folder and click Documents.
2. In the Documents folder, double-click on the Zoom folder. Next, you will see a folder for every date / time that a meeting was scheduled.
3. There will be at least 2 files in the folder. The first file in the screenshot below is the audio recording. The second file is the video recording.
Double click on the file to make sure it is the one you want. If so, rename the file to something meaningful (from the screen above, you can right click on the file name and choose rename).
