Failed to convert - cannot find the files to convert

[devicemanager]

I have a client who has a large amount recording in their app.  The updated to the latest version and all of the recordings need to be converted for some reason?  They are currently in .mp4 format and play when you click them manually but not thru the app.

There is an option to convert and states it can not find the files double_click_to_convert_01.zoom 02 etc

Whats the point of this?  Will they still play natively?  How do I convert the files?

Thank you.
