Is it possible that the tree structure of the personal files of the students can be changed by the student him(her)self?
Tree structure for students (version 3.4.2)
It shouldn't be, only the information contained in their Profile page should be accessible for Users.
Thanks for your answer, but in this specific case they need to be able to do this. Is it possible?
Are we talking about the same thing? General files or Private files?
You want students to be able to upload private files to their personal space and access them? Then you want students to have full control over them?
Look at this Moodle Doc, it could provide you with the information you're looking for.
Otherwise Students won't have access to be able to edit much in the way of general files at all.
