Detalhes
The cleanupUploadStash.php script removes old or broken uploads from the temporary file storage and cleans up associated database records from the table uploadstash. This script can be used to clean up abandoned files in the temporary file stash.

All files created less than the last n seconds ago as defined by $wgUploadStashMaxAge will stay; older files will be deleted.
