Fichier 7zip invisible

Help

Bonjour,
j’utilise Neon depuis plusieurs mois ; il est installé sur un disque dur externe et je suis vraiment très content de cette distribution. installation facile et toutes les applis dont j’ai besoin sont là. Le seul soucis que je rencontre est le suivant : lorsque je copie un dossier crypté avec ARK *.7zip de quelques Mo sur un disque dur du réseau wifi, il n’apparait pas si je n’actualise pas le dossier avec F5. j’ai testé avec un dossier .7zip crypté vide et là, pas de problème, il apparait bien sans actualisation ; idem avec des dossiers non compressés même lourds, pas de problème.
Avez vous une idée de la cause ?
merci à vous. KDE est vraiment un excellent bureau.

I have been using Neon KDE 6.0, plasma 6.1.2 QT 7.6.0, kernel 6.5.0-41-generic 64_bit for several months; it’s installed on an external hard drive and I’m really happy with this distribution. Easy installation and all the apps I need work fine. The only problem I encounter is the following: when I copy a folder encrypted with ARK 24.05.2 in *.7zip of a few MB to a hard drive on my wifi network, I see the copy with a clock as an icon and then nothing. the encrypted 7zipped folder only appears if I refresh the window with F5. I tested with an empty test.7zip folder still encrypted with ark and there, no problem, it appears fine without updating; same with uncompressed folders, even large ones, no problem; they appear as soon as the copy is completed.
Do you have any idea of ​​the cause? And a solution?
thank you. KDE is truly a great desktop.

Hello, I’m moving forward step by step. the problem does not exist with nemo or Thunar. when I run dolphin with a terminal, there is an error message:
dolphin
qt.gui.imageio.jpeg: Not a JPEG file: starts with 0x89 0x50
qt.gui.imageio.jpeg: Not a JPEG file: starts with 0x89 0x50

kf.coreaddons: “Could not load plugin from /usr/lib/x86_64-linux-gnu/qt6/plugins/kf6/thumbcreator/appimagethumbnail.so: Could not load library /usr/lib/x86_64-linux-gnu/qt6 /plugins/kf6/thumbcreator/appimagethumbnail.so: /lib/x86_64-linux-gnu/libappimage.so.1.0: undefined symbol: _ZNKSt7__cxx1115basic_stringbufIcSt11char_traitsIcESaIcEE12_M_high_markEv”
the problem is therefore probably linked to dolphin.
Thanks for your help

solved by adding:
sudo pkcon install kf6-kio-extras and
sudo apt install kio-extras-dev
everything is OK
I deleted Nemo and Thunar
Thanks anyway.
