A free PDF, XPS, DjVu, CHM, CBZ, CBR reader for Windows
Sumatra PDF is a fast, minimalistic PDF, XPS, DjVu, CHM, CBZ and CBR viewer for Windows with no external dependencies, so you can easily run it from a USB drive.
- Simplicity of the user interface has a high priority
- Small and starts up very fast
- Designed for portable use and easily run with external USB drive
I like it for it starts fast and has low system requirements.
A really fast and efficient program, specially good to handle CHM files
