Sumatra PDF 是Windows平台上一款免费阅读器, 它支持打开 PDF, ePub, MOBI, XPS, DjVu, CHM, CBZ 和 CBR 格式. 很小并且启动迅速,优点在于简洁的界面,还有绿色版(单一执行文件,可以在USB上执行,而不写注册表).
all documents are restored at startup if a window with multiple tabs is closed (or if closing happened through File -> Exit); this can be disabled through the RestoreSession advanced setting
printing happens (again) always as image which leads to more reliable results at the cost of requiring more printer memory; the "Print as Image" advanced printing option has been removed
scrolling with touchpad (e.g. on Surface Pro) now works
many crash and other bug fixes
