Sidecar files not automatically detected

[UrbanCoyote]

Hi,

I've written a python script which tags images and writes out xmp sidecar files. These sidecars are IDENTICAL to the ones xnviewmp creates.
Anyway, once my script is done, xnviewmp does not detect them. I need to select images and Metadata > Update Catalog from Files.

I feel this should be automatic as xnviewmp already monitors changes to the directy live (like if you delete, rename or such in finder / windows explorer"

I've got "update when file is changed outside" but this doesn't work.

yeah, I think it should handle sidecards as well

I would also improve clarity of auto (re)import settings:
Settings - metadata - add auto/manual import mode switch

xmp file size or date change?

xmp file size or date change?

just the same as in change detection routine for image files
is there any reason why it could be different?

[UrbanCoyote]

maybe date change detection would be safer?

If one swaps cat with dog in the same sidecar it should be the same size and no change detected
