As you know the GoodRead has a nice feature that allows you to password protect any folder you want, so you can hide stuff , you don;t wand someone playing with your iPAD, to watch.
Guess what I tested that feature. You sure need a password when trying to get into the folder.
When you activate goodreaderusb on your PC (XP in my case) , You can see the files in the protected folder, and drag them into your PC.
So Be careful...
