[digiKam-users] Reread metadata from files: Can this extend to XMP sidecars?

[Maik Qualmann]

If you do not activate "Sidecar filenames are compatible with commercial 
programs" a separate sidecar will be created for each image/video format, even 
if the base name is the same. You need to know whether you really need the 
sidecar BASENAME.xmp for other programs or whether BASENAME.EXT.xmp would be 
better for you.
