An EPS file (Encapsulated Postscript) is a file format usually reserved for industry standards graphics. To open and edit an EPS, you need a program like Adobe Illustrator. If you don’t need to edit it and don’t care about destroying the format, you can also open it in Photoshop and other raster based graphic programs.
However, you can use and EPS without having to open it. You can place an EPS into layout programs like InDesign, Quark, PageMaker, or Word processing programs like newer versions of Microsoft Word by using the “import” feature.
