Description geisserml 2021-07-15 12:17:28 UTC 
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.
