video does not open

I have been a Zoom user for quite a while. I have attended meetings, and also hosted a cople of meetings. All went fine. Two days back, I hosted a meeting, and also recorded it. I got through about 28 minutes, and recording is fine. I restarted it and went to complete. Got a file too. But, the video file does not open. I need this file, to share & use. The filename & path are:

doubleclick_to_convert_01.zoom
and 

doubleclick_to_convert_02.zoom

Message says "cannot find the files to convert" and 'please open the destination folder and rename them to be the above names then double click to start converting' and 'open destination folder' When I try this, nothing happens.

Can you please guide me on how to get the video file?
