When I tried to use this
.Torrent file showed an error
PDF files , you cant scroll down, or use page up or page down to navigate. No option to copy text from PDF
Opened and extracted Rar file with out any issues.
played a .Mid audio file with out any issues
Played an Avi video file – getting struck, and have some problems when you drag to forward. Also no option view full screen.
So you may not use as a primary viewer for some formats.
