External Email - Use Caution

Hello Giuseppe, Try the same command (with lowercase w) or use a+w and then enter your password, $ sudo chmod -R  a+w  $SUBJECTS_DIRPassword: … then test to see if it works to create a file there, i.e., it should not report permission denied ... $ touch $SUBJECTS_DIR/foo … then see if you can remove the file … $  rm  $SUBJECTS_DIR/foo If that works you should be OK. - R.
