What is the recycle bin?
- The recycle bin allows teachers to retrieve course elements they have mistakenly deleted. It also allows those with relevant category permissions to restore deleted courses.
- If deleted items are not needed, they are automatically permanently deleted after seven days (or a time specified by the admin.)
- The recycle bin was the first project funded by the Moodle Users Association. Watch the HQ screencast Recycle bin
How does it work?
1. Before a course teacher deletes an item, a reminder message appears:
2. If you mistakenly click 'yes', all is not lost. Turn editing off or effectively reload the course page or navigate elsewhere in the course then go to the course administration block. The link "Recycle bin" will be visible.
3. Click the link and then click the 'restore' icon to retrieve the assignment or other item you accidentally deleted.
1. Access the category that the course was in before you accidentally deleted it. 2. From the category administration block, click 'Recycle bin'
3.Click 'Restore' to restore the deleted course:
Activity deletion in progress
In Moodle 3.2 onwards, a message 'Activity deletion in progress...' is displayed whilst an activity is being deleted.
Note: The cron should run every minute to ensure that activities are deleted promptly.
How is it set up?
- The recycle bin is available by default in all courses and categories, but the link in the administration block is only visible once something has been deleted.
- Administrators can modify the settings from "Recycle bin in the Site administration, and can decide how long an item or a course will remain available until it is permanently deleted, and make the recycle bin visible in the administration block even when empty. If preferred, the recycle bin can be disabled.
