Nobody helps me.
So I copy all the content of /home/caeclara/intranet-esa-clara.fr/documents/Le Kit de l’entrepreneur/ to a new subdirectory /home/caeclara/intranet-esa-clara.fr/documents/KIT/
And I fill the Base Directory 2 field with : /home/caeclara/intranet-esa-clara.fr/documents/KIT
And I have no more problems about correct notation for spaces and apostrophe…
