XnView Software

I've made a mesh with xnview.db files. I normally use one computer
with my xnview.db on Google Drive by setting the Folder Catalog to "Custom"
and selecting the appropriate folder within my Google Drive folder.
But for few days I've been working on another computer on which I forgot
to define the setting and left it with the default User (System).
Is there a way I can merge the 2 xndview.db files so that I can put
the merged one on my Google Drive folder?
Thanks

and what are the changes? Categories?

With the second computer I've tagged many other photos, some on a different
external disk, and added some
new categories. I see different photos with each computer. Actually,
if I select the Google Drive xnview.db file with the second computer
and restart xnview, I see the same as with the first computer, but then
do not see the ones I tagged with the second one.

could you send me the 2 .db?
