Sure its pretty easy..
backup then open the modules' BxFilesPageView.php
after:
$aUnit = array(
add:
'moduleUrl' => BX_DOL_URL_ROOT . $this->oConfig->getBaseUri(),
'fileUri' => $this->aFileInfo['medUri'],
'file_type' => '_blank',
save and close.
&& the modules base template view_unit.html
beside __fileTitle__
add:
<a href="javascript:void;" onclick="window.open('__moduleUrl__download/__fileUri__', '__file_type__', 'width=500,height=380,menubar=no,status=no,resizable=no,scrollbars=yes,toolbar=no,location=no')">download</a>
with this new info you should be able to add your own language key if you need it....you can test it before you try it here(new window):
