Question for integration with other programs on KDE Neon

[4i4obengy]

Installed XnView on Linux Mint, double-clicking on a docx or zip file is opened in the respective programs "Onlyoffice" and "Ark". This does not happen in KDE Neon. What is installed in a Linux Mint that is not in KDE Neon?

Which XnView MP (version 99.7?) Linux download (TGZ, DEB, AppImage, Flatpak) did you install, I ask in case that is relevant?

This does not happen in KDE Neon. What is installed in a Linux Mint that is not in KDE Neon?

You are asking about the files contained in a Linux Mint install relative to KDE Neon, or do I misunderstand?

For which version of each, if that could also be relevant? If so, you would probably be more likely to obtain help quickly by posting on the Linux Mint forum, it is very active and there are a lot of knowledgeable people posting there.
