Zoom quit as recording was converting

HI!  I see you posted this a little while ago but in case it happens again or someone else reads this, it may be worth finding the file in your file viewer and checking the name of it carefully.  It seems that Zoom has a mechanism for protecting files that were not able to convert to MP4s fully due to computers shutting down.  You may see that is saved with a name that is an instruction like mine was.  The program named it "double click to covert".  After I double-clicked the file, it was transferred into a version I could use as usual.  Maybe this will work for others.
