The PC file viewer software provides you with an application to view popular PC file formats such as Microsoft Word, PowerPoint, Excel, Lotus 1-2-3, and AutoCAD. Use the viewer to choose a file and to copy and paste information from the viewer to another application, such as a text editor. CDE applications will be able to identify these filetypes and launch this application by double-clicking on the icon in your mail attachment or from File Manager (dtfile).
