Description Henning 2024-03-24 19:21:33 UTC 
I am trying to move a few files over 1GB from an external SSD connected over USB to my internal storage.

Both my internal storage and the external SSD are encrypted. On the external SSD there is another Fedora Kinoite install, so the /var/home/$USER belongs to another user, meaning I need to open it with "admin:"

now I try to move a few ISO files from that users home to my home, and I start a Ctrl+X Ctrl+V from the privileged admin: tab to a regular user tab.

A "file is moved" notification appears but nothing happens, either the message is not updated, or the process does not work.

I did not get any error logs but will try to get some soon.

Comment 1 Henning 2024-03-24 21:32:47 UTC 
I was able to reproduce this 3 times, meanwhile a "sudo mv" worked in a few seconds, for a 2GB movie file.
Comment 2 John Kizer 2025-01-02 19:00:36 UTC 
I can reproduce on Fedora KDE 41, kio-admin 24.12.0. Tagging as critical since moving or cut-and-pasting a file can result in loss of the much of the file's contents.

I have done some more tests.

Using `kioclient cp admin:/root/xxx.iso` copy the file correctly.

So i think this might be related to Dolphin's kio-admin integration part?

https://invent.kde.org/system/kio-admin/-/merge_requests/9 would probably fix this but I wasn't quite happy with the code yet.
