When middle clicking a .zip file, having QGIS set as second-favourite program, it instead opens the archive in a new tab. When double clicking the archive, it opens in Ark and not "inline" in Dolphin. This is odd, I am not sure which you would prefer and it likely depends on your workflow. Operating System: Fedora Linux 40 KDE Plasma Version: 6.1.4 KDE Frameworks Version: 6.5.0 Qt Version: 6.7.2 dolphin-libs-24.08.0-1.fc40.x86_64 dolphin-plugins-24.08.0-1.fc40.x86_64 dolphin-24.08.0-1.fc40.x86_64 ark-24.08.0-1.fc40.x86_64 ark-libs-24.08.0-1.fc40.x86_64
Can reproduce with usual archives. Operating System: Arch Linux KDE Plasma Version: 6.1.5 KDE Frameworks Version: 6.5.0 Qt Version: 6.7.2 Kernel Version: 6.10.7-arch1-1 (64-bit) Graphics Platform: Wayland
I suppose Dolphin settings should have such toggle for viewing archives.
Fixed in https://invent.kde.org/system/dolphin/-/commit/2b1906eeeabaf91b856d46e72390ae811747ec39 by Jin Liu for the upcoming December Dolphin release 24.12. We did not add a toggle and simply decided to be consistent with how it works for normal files. If one has less than two archive applications installed, it will keep opening archives in a new tab instead.
