Sumatra PDF 3.4.1

Sumatra PDF has a minimalistic design, and its simplicity is attained at the expense of many other features. As is characteristic of many portable applications, Sumatra takes up little disk space (compared to Adobe Reader's 27.5mb setup file), and it starts up rapidly. It was designed for portable use in the sense that it's just one file with no external dependencies so you can easily run it from external USB drive.
