I'm afraid that I need to ask for help, I am trying to create a backup file of my collections in case I lose my ereader.

Calibre's frequently asked questions says in the "Can I use both calibre and the
SONY software to manage my
reader?" section that the reader uses a single file to keep track of meta information like Collections.

Does anyone know the name of the file that keeps track of all of this?
