Publishing your documents into PDF (Portable Document Format) ensures that your files retain the formatting that you made and the contents are not altered. This is very essential if you’re distributing documents to colleagues or other employees. And to be able to view these PDF files, you must have a PDF reader installed. Foxit Reader for Windows is a free and lightweight PDF reader.
Once installed, you can save office 2007 files as PDF by clicking on the MS Office Button , then point to Save As and click the PDF or XPS option. Give the file a name and you may check the Open file after publishing checkbox. If you need to edit your PDF file, open and edit the office 2007 file and save it again as PDF. You may overwrite the existing PDF file.
