Hello,  I would also like an answer to this question.  My Customer wants the FIELD Tab to be displayed by default.

at the path: C:\Program Files\Laserfiche\Web Access\Web Files\Dialogs\ImportDialog.aspx

I found this section which might be relevant but would prefer a definitive answer rather than use trial/error to work this out.  Thanks
