AWS s3 sync Fails with Extant File (debug log is attached)

Question

I’m attempting to use the CLI to backup a file on a Windows 10 PC to an s3 bucket. The command (in a command file) has worked for a few days but today it failed, saying the file doesn’t exist. This problem recurred after a reboot and after upgrade to the latest version of the CLI.   
  
I’ve attached the debug log which is preceded by a chkdsk and followed by a confirmation that the file exists. Any comments would be much appreciated.   
  
Thank you,

Answer

For anyone else who has this problem, I see that the s3 sync command only syncs _directories_, not files. I was trying to sync a file. I suspect that my original version worked properly because I was using cp and not sync. I suspect that I changed cp to sync and then forgot that I had done that.
