Are you sure your moodledata directory is where you think it is? FileZilla isn't showing the complete remote path but on your install 'moodle' is under 'htdocs' and 'moodledata' is a directory above. On FileZilla they are both shown at the same level. If that's the correct location for moodledata then I would expect to see an 'htdocs' directory in the same place.
