SUMMARY *** Dolphin creates temporary files in /tmp when thumbnailing image files from "smb:" mounts (r/w or r/o). Over time, these files fill /tmp eg: -rw------- 1 ubuntu ubuntu 0 May 16 11:38 dolphin.ExHKzo -rw-rw-r-- 1 ubuntu ubuntu 8577350 May 16 11:38 dolphin.ExHKzo.part -rw------- 1 ubuntu ubuntu 0 May 16 11:38 dolphin.IeQYAj -rw-rw-r-- 1 ubuntu ubuntu 14409948 May 16 11:38 dolphin.IeQYAj.part *** STEPS TO REPRODUCE 1. Ensure 'preview' is set to enabled for remote files in dolphin 2. Open smb mount - eg smb://192.168.1.11/photos2022_RW/3_Mar/ 3. Observe as thumbnails are generated increasing number of files in /tmp/ - these are never removed OBSERVED RESULT -rw------- 1 ubuntu ubuntu 0 May 16 11:38 dolphin.ExHKzo -rw-rw-r-- 1 ubuntu ubuntu 8577350 May 16 11:38 dolphin.ExHKzo.part -rw------- 1 ubuntu ubuntu 0 May 16 11:38 dolphin.IeQYAj -rw-rw-r-- 1 ubuntu ubuntu 14409948 May 16 11:38 dolphin.IeQYAj.part EXPECTED RESULT No objection to files being created in order to thumb - but should be removed post thumbnail SOFTWARE/OS VERSIONS Linux/KDE Plasma: KDE Plasma Version: 5.24.4 KDE Frameworks Version: 5.92.0 Qt Version: 5.15.3 ADDITIONAL INFORMATION Dolphin version 4:21.12.3-0ubuntu1 Note: Does not appear to happen when mounting the same location via sshfs - only via smb Note2: Does appear some of the files are created and subsequently removed - but not all
I'm seeing this too. It's not difficult to fill up /tmp by browsing a photo collection via the smb kioslave. Should this bug be reassigned to the kioslave?

Still present in plasma 6.2.5 / dolphin 24.12.3. This renders the smb:// kioslave near unusable. Combine this with the miserable ui-freezing behaviour of plasma / dolphin on non-kio network mounts (too many bug reports to count, going back many years) and the "just use kio, that's what it's for" comments that issue keeps attracting... What purpose exactly does a file manager that can't gracefully handle network mounts or thumbnails serve, in 2025?
