is the jpeg file a mess? <br>
There are several dates (modify, create, file modification and file access) and <br>
information is reduntant, but I don't see conflicting date/time information.<br>
<br>
What I started with is overwriting Original Date by Create Date, but doing it <br>
with the BQM for several 10'000 files in many different folders takes quite <br>
some time, so I decided to stop it and have a look to find out what really is <br>
the case.<br>
<br>
A exiftool-based script would be faster and (for me) easier, but what should I <br>
keep / remove exactly? And: the exiftool command I mentioned (see last <br>
message) didn't change any date/time information, did it?<br>
<br>
Thank you!<br>
<br>
Best,<br>
Bernd<br>
