File Formats and Plug-ins

Wherever possible, Noridian will post information on this site in open-standard, accessible formats (e.g., HTML). However, there are some areas of the website where specialized media must be used and plug-ins or special viewers may be needed to access the content. Below is a list of file types that are used on the website as well as further information on getting the plug-ins.

Note on viewing and downloading files: Depending on the configuration of user computer, files of the types listed below may:

  • Open inside of web browser,
  • Open in a new program window, or
  • Ask visitor where to save file. If user would like to download a copy of file to his/her computer, right-click (on Windows) or command-click (on Macintosh) and choose "Save Target As…" (IE) or "Save Link As…" (Firefox / Mozilla). This will allow user to save a copy of file to computer rather than having file open inside web browser
