Code

modules/file/file.field.inc, line 191

<?php
function _file_generic_settings_file_directory_validate($element, &$form_state) {
  // Strip slashes from the beginning and end of $widget['file_directory'].
  $value = trim($element['#value'], '\\/');

  // Do not allow the file path to be the same as the file_directory_path().
  // This causes all sorts of problems with things like file_create_url().
  if (strpos($value, file_directory_path()) === 0) {
    form_error($element, t('The file directory (@file_directory) cannot start with the system files directory (@files_directory), as this may cause conflicts when building file URLs.', array('@file_directory' => $form_state['values']['file_directory'], '@files_directory' => file_directory_path())));
  }
  else {
    form_set_value($element, $value, $form_state);
  }
