<br>
So is it a problem in writing the xmp file or reading from them on the<br>
new location?<br>
<br>
I have simmilar problems. Digikam writes xmp files quite fine, but never<br>
reads from xmp automatically if they are changed by another program<br>
(like darktable). I have to sellect the album/file and hit reread<br>
metadata from external file to get it working.<br>
<br>
I hope this will be fixed in upcomming digikam 5.<br>
<br>
Regards<br>
Martin<br>
