Hi, just wondering if anyone's delt with one of these before.
Code:
http://www.vitalsource.com/software/vbk/
I've already done a google and forum search. Also, just as a potentially useless tidbit, using a hex editor on my .vbk file shows some ascii strings including JFIF (starting at address 6decimal) and AppleMark (starting at address 24decimal)

k bye
