This is certainly possible...  do you wish to embed PDF files in a page, open them in a new window, or offer them for download as a link?

Please give me both possibilities, it would be a great help.    thank you...

1.  To embed a PDF file in a webpage...  in Step 3 - Page Creation, drag an 'HTML and Widget' object onto your page...  double-click the object to open the HTML Code window...  From the Widget list on the right of the screen double-click the 'PDF File' object...  in the 'File URL' box enter the URL to the PDF file which exists on your server or on the Internet

2. To open a PDF file in a new window...  in Step 3 - Page Creation, drag a Text Object onto your page...  double-click the object to open the text formatting screen.  Include as much text as you would like to describe the PDF file.  Highlight some or all of this text with your mouse and then click on the 'Insert Link' icon on the top toolbar...  in the screen which opens select 'File or URL' from the list on the left-hand side, and enter the path to the PDF file as appropriate in the field on the right-hand side...  finally, select the radio button 'Open in a new window'

Thank you, will try as soon as poss...
