What is SumatraPDF? (from Krzysztof Kowalczyk)
Sumatra PDF is a free PDF, eBook (ePub, Mobi), XPS, DjVu, CHM, Comic Book (CBZ and CBR) reader for Windows. Sumatra PDF is small, portable and starts up very fast. Simplicity of the user interface has a high priority.
Overview
SumatraPDF is a program developed by Krzysztof Kowalczyk. The most used version is 3.0, with over 98% of all installations currently using this version. Upon installation, it defines an auto-start registry entry which allows the program run on each boot for the user which installed it. A scheduled task is added to Windows Task Scheduler in order to launch the program at various scheduled times (the schedule varies depending on the version). The software is designed to connect to the Internet and adds a Windows Firewall exception in order to do so without being interfered with. The main program executable is sumatrapdf.exe. The software installer includes 26 files and is usually about 9.14 MB (9,581,024 bytes). In comparison to the total number of users, most PCs are running the OS Windows 7 (SP1) as well as Windows 10. While about 44% of users of SumatraPDF come from the United States, it is also popular in Germany and France.
