How do I open the "double click to convert" file?

It seems that the downloaded recording file from Zoom has not yet been converted to a playable format. Normally, a Zoom recording is automatically converted to a standard format such as MP4 or M4A once the meeting is over.

It may be that an error occurred while downloading or converting the file and some files are missing or corrupted. In this case, the file cannot be converted to a playable format.
I recommend that you follow the steps below to try to recover the file and convert it to a playable format:

1. verify that all parts of the recording have been downloaded: The recording may have been split into multiple parts if it was longer than 2 hours. Make sure that all parts were downloaded and are in the same folder.
2. convert the file manually: open the folder where the downloaded recording is stored and look for the file "double_click_to_convert_01". Right-click on it and select "Rename". Change the name of the file to "double_click_to_convert_01.zip" and confirm the change. Then open the ZIP file and extract the contents to a new folder. Search for the file "index.html" and open it in your browser. From there, you can manually convert the recording to a playable format.
