Hi. I'm using Moodle version 3.9.2
I have Moodle hosted on a "Cloud Site" plan. The maximum number of files that I'm allowed to have is 600k.
My file usage had crept up to over 80% of my limit. Just when I was wondering how I would solve this problem, my file usage fell to just over 20%. I didn't delete any files or make any changes that caused this drop. I've not noticed any change in the site since the disappearance and none of the files that disappeared have been missed. So, this was a great turn of events. But I want to understand what happened so I asked the host. The host said, "We would like to inform you, that we have thoroughly reviewed your case, and it seems that Moodle automatically removed the old unnecessary files from the moodledata1 directory."
This has left me puzzled. The only setting within Moodle that I can find for automatic file deletion is "Clean up". I have the settings within "Clean up" on the default settings of: "Clean up temporary data files" set to one week and "Clean up trash pool files" to one day.
My file usage is still low but is starting to creep up again. So, I'd like to understand how Moodle automatically removes unnecessary files so I can avoid going over the limit. All help much appreciated!
