In my Mylio library I have an PSD file named
Winter sun in Katoomba_collage.psd which has nearly no metadata saved in it. However its source photo named
Winter sun in Katoomba_IMG_9814.jpg has lots of Metadata.
exiftool I created from
Winter sun in Katoomba_IMG_9814.jpg a sidecar XMP file, named it
Winter sun in Katoomba_collage.xmp and put it next to the PSD.
I was hoping this would give the PSD the needed metadata, but what happened? The XMP got silently deleted by Mylio!!! How can I add a XMP to a file which does not have a XMP yet?
ps: An additional strange thing is that I can add metadata to the PSD in Mylio (e,g, via rating or flagging). These metadata are persistent, but are not saved to a XMP sidecar file and are not saved in the PSD either. Where the heck are they saved???
