eFob Portable PDF Software

On this page I am listing the very best portable PDF software for usb thumb drives, SSD Flash Drives, iPads, and mobile devices.
The portable software I'm listing here is either portable PDF software I use myself or the best available without charge or open source portable PDF software.
I have both Foxit Reader and Sumatra PDF installed on my USB drive and I like and use them both. Having the convenience of an instant PDF reader without having to rely on Adobe is bliss......
