Hello, Séverin Terrier
I never received any notification that you replied to this mail (or I just might have missed it) .
So I apologize for this late reply and thank you for your concern!
Yes I am saving all my Moodle files "as are" to make a backup.
Thank you for answering my question.
I had transferred all the file to my computer using FTP, but I will now delete everything that is superfluous.
Best regards, keep safe.
