You can open and view PostScript or Adobe Acrobat PDF files. PS Viewer lets you access previously viewed files by storing the names of the last four files opened. When you view a document, you can change the page setup to suit your needs. You can also use the Zoom tools to enlarge or reduce the viewing size of the document. PS Viewer maintains summary information about each file, such as the path and filename, title, and creation date of the document.
