This plugin provides approximate disk usage by Moodle courses.

There are 2 known shortcomings with this plugin

  • If the same file is used multiple times within a course, the report will report an inflated disk usage figure as the files will be counted each time even though Moodle only stores one copy of the file on disk.
  • If the same file is used within multiple courses it will be counted in each course and there is no indicator within the report to inform the user if they delete the course or files within the course they will not free that amount from disk.

It should be possible to improve the report to address these issues - we'd greatly appreciate any patches to improve the plugin!

To improve the performance of the total disk usage check, you should configure the pathtodu in your installation:

    Hi Dan,
    can you provide me a SQL Query for the Course size as i am working on some ad hoc reports to count Total Sizes by all Coursers(Including the Back up Size), Also Include the Category and Sub category in the reports.

    @Life - try using the moodle forums to ask for that sort of support - someone else might have the time to put something together for you.

    1. This plugin shows 200 less courses that I have in total (show on the moodle registration page), what can explain this?

    2. What does this mean "Courses that do not use any file storage have been excluded from this report." I can see 0MB courses on the list also.

    This plugin looks at the files table in moodle - if your courses do not have any records in the files table they will not show in the report. It is also possible that some courses have entries in the file table with 0 filesize on disk and the report also performs some rounding.

    Just ran the latest version and it reports the courses fine, but when I click 'view stats' each course shows 0MB for each category listed?

    @chris - that's a bug with the sql being used to generate the stats - there's a fix in the github branches for it.

    Is this plugin compatible with Moodle 3.8?

    should be - but no one I know has tested it to make sure. Feel free to help by testing and reporting any bugs/issues you find to our bug tracker (linked above.)

    We are seeing enormous usage by users....but when we check their private files, there is relatively few items...
    Any thoughts?

    typically that means they have a lot of backups stored in the user private backup area.

    Hi, thank you for your plugin, it's very useful ! For information, I installed it on Moodle 3.8.2 and it works fine.

    @Jinxing Chen - yeah, we've got the same version on a few 3.9 sites already too - must be time to update the plugins db!

    Hello and thanks for this good plugin. Problem I see is that I don't know how to refresh the plugin. For example, I have found out that a the file sizes in private space of a user, X, is large and he has deleted the files. When I rerun the course size in report section, I see previous results quickly. Seems that it has cached the previous results. I also tried to purge all cache via Site administration-> Development-> Purge caches but has no effect.

    @Mahmood - the current version of this plugin shows "live" data - it doesn't cache specific disk usage like private file areas, but Moodle doesn't physically remove files straight away on deletion - it "flags" them for deletion and then relies on various cron processes to delete the files. Try asking in the forums for more details or do a search for "Moodle Trash files" and it might show up a few related posts.
