According to the api docs, #default_value is a supported property of the file form control.

However this isn't working in my testing. Example:

  $form[$fieldname] = array(
    '#type' => 'file',
    '#title' => t($field->label),
    '#description' => ($node->$fieldname ? t('"%filename" has been uploaded. If you upload another file, the current file will be replaced.', array('%filename' => $node->$fieldname->filename)) : '') . t($field->description),
    '#required' => $field->required,
    '#weight' => $field->weight,
    '#default_value' => 'TESTING.txt',
    );

I agree, its not working here either

turns out it is not supported on most browsers due to security issues

(ie: you could set the default value to be c:\somesecretfile, hide the file field in a no-display div and then just show the submit button...)

Yeah. See Input File Value thread on Evolt.org for further details.

The value type in file input fields is not supported by any browser that I know of for these reasons. Doesn't make sense for Drupal to support it either. Setting to won't fix.
