Backup of Inkpad 3 database and annotations

Hello everyone,

I am looking to factory reset my Inkpad 3 due to a frozen home screen. I would, however, like to backup my book database, highlights and annotations, and my fonts.

Does anyone know if I can simply copy the following files/folders to my computer, then copy-paste them back to the reader after the reset?

/system/config/books.db
/system/explorer-3/explorer-3.db
/system/fonts/

Thanks for reading!
