Debian Trixie with KDE Plasma Deleting files from a NFS mount downloads the files and wants to put them in the Trash Can of the Laptop. This does not happen on the same Laptop with GNOME. These are movie files and it would take a long time to delete, plus I don't have that much disk space on the Laptop anyway. This is a bug. Dolphin should not treat NFS as a local storage and it should not attempt to download files to local client before deleting remote files on NFS. It should just delete them.
For what it's worth, I'm not personally sure but this seems potentially related to https://bugs.kde.org/show_bug.cgi?id=493640
