We encountered a problem with our Moodle installation on Monday 2 June and whilst investigating discovered that our filedir folder is very large (129GB). Since then the folder has increased by 7GB which to me is extraordinary given the minimal activity that is reflected in the logs . We have identified the files that are 'gigantic' but they are encrypted.
Is there any way of finding out what those files are and in which category, sub-category or course they are residing? This would help us to determine what is going on.
