Where does Reader App save its files?

[diddy]

Hi,
Can somebody please explain where the Mac Reader App saves its files? With the old Reader Library App there was a kLibrary.xdb file under /Users/username/Library/Preferences/Sony Cooperation/Reader.

I do find a /Users/username/Library/Preferences/Sony Cooperation/ReaderDesktop folder with nothing in it except a ticket folder which is empty as well (and there are no hidden files).

So where does Reader App save all the annotations etc?

The reason I ask is twofold:
1) I need to completely uninstall the Reader app. I uninstalled it the normal way and installed it again, but all my books and annotations were back again. I want a clean start.
2) I want to keep a backup of the annotations file as it seems like the Reader App corrupted it when syncing with the T1 (All highlights are duplicated 20 times or so).

Thanks,
Diddy
