Noel,
as I said, the file was in an endless sync with the One Drive cloud server so I could not ignor it. Solved it by the tried and proven method. Delete the offender.
Up dated system image, just in case.
Turned off One Drive on my computer.
Logged into MS Onedrive on the cloud.
Deleted the file on both the cloud and my personal computer.
Rebooted.
The file came back but my sync problem was gone. All is well. No idea what happened to cause this.
Gil.
