<div dir="auto"><div>Thank you for your reply. It is a windows 10 operating system that I'm using Digikam on. Looking back at the older files, when dates prior to 1970 we're added using Digikam, windows filled them with blanks on the file. Seems a recent windows update isn't allowing null values on the file dates and throwing the error. I unchecked the update last edit date option on the tool and it's running correctly for the metadata now. Hopefully they will continue to upload to Google photos correctly.</div><div dir="auto"><br></div><div dir="auto">Thanks again for your reply</div><div dir="auto">David<br><br><div class="gmail_quote" dir="auto"><div dir="ltr" class="gmail_attr">On Wed, Jul 21, 2021, 2:13 AM Maik Qualmann <<a href="mailto:metzpinguin@gmail.com">metzpinguin@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">One more addition, only the file date is a problem, the date in the image <br>
