.PS File

The ps file extension is typically associated with Adobe PostScript, a dynamically typed concatenative programming language, best known for its use as a page description language in the electronic and desktop publishing areas. Once the de facto standard for electronic distribution of final documents meant for publication, PostScript is steadily being supplanted in this area by one of its own descendants, the Portable Document Format (PDF).

You may occasionally encounter files containing a stream of PostScript data. These files may typically be sent directly to a PostScript compatible Printer for printing.

More commonly, you may encounter Encapsulated PostScript files (eps) which typically contain a section of a page or an individual graphic.

MIME types for ps files:
application/postscript
application/ps
application/x-postscript
application/x-ps
text/postscript
application/x-postscript-not-eps

Files with ps file extension can be commonly found as to-be-printed final versions of documents and other publications saved in Adobe PostScript language for PostScript printers.
