ActivePDFView is a lister plugin (WLX) for Powerarchiver. It allows the user to preview an Adobe Acrobat PDF file in either the QuickView panel or in the floating TC lister window and with much of the utility of the standalone Acrobat viewer. The free Adobe Acrobat Reader must be installed on your system before attempting to use ActivePDFView to view a PDF.
