Hardware and performance

This is the down side of the intelligent user file management of Moodle. They have their own structure, you can't easily connect them with the courses or activities they originate. There are a whole series of additional plug-ins, mostly from third parties. But before diving in to all that you look at the size of files under moodledata/filedir/ that is where all the uploaded files go.

WARNING: Don't change anything in that cryptic directory tree!

Your teachers might be making backups themselves and those backups go to their private area ... which admin level user can't see.

So query would help ... query mdl_files table for all .mbz files

mysql -u root -p'pass' -e "use moodle;select userid,contenthash,filename,filearea,filesize,timemodified from mdl_files where filename like '%.mbz' order by filesize DESC;" > backups.txt; cat backups.txt;wc -l backups.txt

Teachers could have multiple backups and some very old ones that could be removed.

Also, if running a version of Moodle that has it, recyclebin and admin has 'cleaned up' site .. removing categories and courses in those categories rather than moving those courses to another category.   For a while until cron job/task moves those recyclebin backups in to trashdir, more space used.

There is a command line utility called 'moosh' that has an option for deleting files which removes them from sea of files in /moodledata/filedir/ *and* updates the mdl_files table.
