Viewers, Plug-Ins and Readers

The Postal Regulatory Commission (PRC) provides information on its website in a variety of file formats. Most of these file formats are easily read and displayed by standard web browsers or word processing programs. There are, however, some files whose formats have been specifically developed for transmitting and displaying special content, such as multimedia or very precisely defined documents, and may require the use of additional software to be presented correctly.

Visitors to the PRC website can download and install on their computers free add-on programs called viewers (also referred to as plug-ins, readers or players) that will enable their browsers to display or play the content of these files. The special file formats that are currently used on the PRC website include Adobe Acrobat, Microsoft Office, Windows Media, and RealPlayer. Hyperlinks for downloading the required viewers are provided below.
