I realized, that my trash bin never got deleted. Which makes sense based on the documentation, the default setting 'trashbin_retention_obligation' => 'auto' and my users who do not have any quota being configured.
Now I changed the setting to 'trashbin_retention_obligation' => '30,180',in config.php and even after deleting files, adding new files and ensuring the the cron job is working correctly every 5 minutes, I still have files in my trash bin older then 180 days. Actually I have still files in there from the date I installed the trash bin app.
I also read lots of articles and the documentation about the issue, but honestly saying, there werer so many different opinions and views.
How can I troubleshoot this, how can I enforce the deletion of old files ?
I am on NC 17.0.2 right now.
Thanks
