assignment -> using filemanager, deleting a folder that contains a file seems to delete the folder but renderering the folder tree has notices and deleted folder is rendered.

in assignment type upload:

• create a submission with files
• grade the submission with dirs containing files..
• submit and edit the files again - this time delete 1 dir that contains a file.
  1) the delete seems to work fine. i suspect the delete doesn't really happen as i see the dir and caught a glimpse of its file during the page rendering back in the grading page.) -> shouldn't there be a confirmation since theres files inside the directory?

• submit and you should see the notices below:
