Plugin create insane amount of pdf files - Course size become twice big

[RoyalZefa]

Then i check my course size i see that assignfeedback_editpdf size very very big, but no one use it in this course. I loose connection to my moodle site and in hurry try to delete temp/assignfeedback_editpdf folders inside. Then i got back to my site i delete plugin and delete some students answers. And i disable assignfeedback_editpdf cron job. Right now i run cron job to clear some trash can files etc, but it not worked good. I delete manual content from trashdir and it free some space. But in course size it still presents.
UPD. I think it is not plugin problem. I found same problem on https://tracker.moodle.org/browse/MDL-69570
Riht now i have some orphan file and big autobackup(change it to file server)
Sorry!
UPD 2:
I clear all this file by using smoosh command:
moosh file-list -i 'component="assignfeedback_editpdf"' | moosh file-delete -s
moosh file-delete --flush
It delete all this files. You can check this file using smoosh and look on all file in you course.
Similar to this i delete all ghsot autobackup.
So it was me who didnt know about annotation feature. And you plugin very nice!

I am experiencing a similar / the same problem: The plugin needs a lot of disk spaces (up to 3.5 gigabytes per course) even after a course reset has been done, i.e. all the students' uploads are deleted. Unused files seem no to be deleted by the plugin.
