|Ghostscript and GSview|
To read postscript (.ps) files, you will need a postcript interpreter (Ghostscript) and a postscript viewer (GSview).
To obtain these, go to the Home of Ghostscript. Follow the link Obtaining AFPL Ghostscript x.xx (where x.xx is the highest number available). Go to the windows section and download and install "gsxxxw32.exe" (where those x's are the same as before).
Just a few lines below, on the webpage from which you downloaded Ghostscript, you can download GSView x.x (where x.x is the highest number available). To do so, download and install the file gsvxxw32.exe (where those x's are the same as before).
