SumatraPDF — The Complete Guide: A Very Light, Fast Free PDF Reader for Drawings and Standards
SumatraPDF is an open-source document reader (GPLv3) for Windows. It is not an editor and adds no unnecessary layers — it just opens files, fast. When you open dozens of drawings and standards a day, the difference shows.
