SUMMARY KIO places downloaded files in the permanent cache directory `~/.cache/kioexec/krun/`, which persists across different sessions and is never cleaned up by the system. Users have reported this directory to grow enormously over time, unless manual measures are taken. A persistent cache seems inappropriate for KIO downloads. Instead, regular temporary files should be used, placed in the system's dedicated temporary directory (QStandardPaths::TempLocation, https://doc.qt.io/qt-5/qstandardpaths.html). Temporary files have the advantage that they are cleaned up automatically on reboot. Therefore, I would suggest to remove `~/.cache/kioexec/krun/` entirely and modify all components that currently rely on this directory to use temporary files instead. STEPS TO REPRODUCE Invoke a KIO download. OBSERVED RESULT The file will get placed in `~/.cache/kioexec/krun/`. EXPECTED RESULT The file should be placed in the temporary directory of the operating system.

Fully agree. I found two videos in the directory which I am not even sure I opened with a KDE application aside from Dolphin. I might have opened them directly from the phone's DCIM directory. In any case, this is an unexpected and insidious behavior, and might cause serious problems for non-CLI-savvy users as there is no way to delete the cache on the GUI.
