Description Henning 2024-09-17 14:44:04 UTC

In Dolphin, if I associate a .qgz file to open with QGIS, I get asked "set zip files to be opened with this app?"

The .qgz files are project archives of the QGIS geodata analysis program. They are probably compressed with zip, but should be a different file type.

not sure where this can be done.

Adding a file association manually didnt work, but I didnt log out yet.

Fedora 40 Kinoite (KDE Atomic)
QGis 3.34.10

Thank you for the bug report!

Applications should register their file types with the shared mime database (see https://www.freedesktop.org/wiki/Specifications/shared-mime-info-spec/) to have their file formats be recognized. This is also how it works for other file formats that are compressed, like odt.

I can see in the QGIS repository that the deb and rpm packaging materials do contain the required information (e.g. https://github.com/qgis/QGIS/blob/master/debian/qgis.xml). Given that you use Kinoite, I assume that you installed QGIS using Flatpak. In my testing, the Flatpak version of QGIS did not seem to properly install this file, while the distribution-provided deb package did. As soon as I installed this version, the file was recognized as a QGIS project file.

Please report this issue to the provider of your flatpak. (In case you installed this from flathub, that would be the QGIS flathub repository at https://github.com/flathub/org.qgis.qgis) so that this can be properly fixed. Thanks!
