i have problem with local-hyperlink like "c:\text.txt" in Microsoft Office
Adobe PDF don't understand these local-hyperlinks.
doPDF does not support detecting files as hyperlinks unfortunately. However we have another product called novaPDF that can do this for you so you can give it a try. Please access this article for more details on detecting hyperlinks in the PDF: http://www.novapdf.com/kb/create-active-pdf-links-using-novapdf-professional-68.html
