The books downloded to the reader through the desktop kobo software (not via ADE) end up in the koboreader.sqlite file (in the .kobo folder on the reader). That's where the 100 free books are as well.
The books in the desktop seem to be in a kobo.sqlite folder in the user/appdata/local/kobo/kobodesktop edition folder (I'm using Vista so it may be different for 7)
