Hi,
This is a trivial error but it happens quite often as by the time files accumulate in the root directory and it's convenient to organize with folders...but has it ever been tried or considered to automatically preserve a link to a file when it's moved from a directory to an other one ? Maybe by using virtual directories (the file stays physically to the same place) so teacher haven't to fix every link..
Maybe i don't see the technical or functional problem and i'll be happy if someone point it out to me, but i think it'll be a great improvement..
Thanks, Julien
