i have a number of course that have been upgraded progressively from the old 1.9 days to Moodle 2.5
I want to get rid of the legacy files, because they are causing the backup files to swell to stupid sizes in the 1-3GB range.
But nothing seems to work. Turning them off, doesn't stop them entering the backup. Importing into a new course and then backing up, also doesn't prevent them showing up.
I have seen a lot of talk about this and this tracker issue seems to be about it.
Is there any way to kill legacy files, so they don't end up in the backup file?
