can't move files to the folders

I've installed Ubooquity on a Raspberry PI 3A+ on DietPi.

Every thing as gone fine and Ubooquity is opening on my browser and i've mounted the PI as a hard drive on windows.

BUT, when i try to move files from my laptop to the /comic/ or /ebook" folders, i cannot write

I've changed the "samba" network parameter with FTO, connected and tried to CHMOD. But there are no  changes in the rights and i cannot move files by FTP too.

What am idoing wrong ?....ideas ?
