Question
How does sidecar work in XnViewMP?

I have clean XnViewMP and enable "Update or create XMP sidecar" in Settings,
but jpg/png files continue to overwrite and no sidecars creates.

xn_sidecar.png (7.95 KiB) Viewed 707 times

For example in Lightroom it is enough to enable this setting

You add a keyword?

my bad, I did not dig deep enough

Currently, XnView doesnt use editing parameters from .xmp

I was excited about Lightroom's ability to write image editing data into sidecars (to use it as non-destructive editing).
Unfortunately, it looks like I was not aware about limitations of this feature:
- works only for camera RAW files
- works only withing Adobe software

XnViewMP saves regular metadata in sidecars as expected.
