Where are imported books saved in Windows?

[f4wired]

I've imported a book and deleted the original file. The imported book is still accessible through Thorium so I presume the file is being copied and stored elsewhere. Where is it being stored? The program is in C:\Users\{NAME}\AppData\Local\Programs\EDRLab.ThoriumReader but i can't seem to find another copy of the book anywhere.

Nevermind, they are under AppData\Roaming\EDRLab.ThoriumReader\publications\

There is a Save a copy of the file option available from the Book information panel. See the Function section of the Thorium Reader Documentation website.
