My Mom got the Kobo eReader (Wireless) device two years ago for Christmas, and while she really enjoyed it, there were just too many books on it to find the recent ones that she purchased. I was recently given the device to try to find a way to remove the old books and if possible, add (import) new ones
I know from looking at the tech specs, that the device supported EPUB and MOBI formats, so I downloaded some free books from Project Gutenberg in the EPUB format.
Please Note: At the time of this writing, I am using Linux Ubuntu 11.10 (64bit) and the Kobo is using software v1.9 (r25373, March 29, 2011).
Following these steps I was very successful in removing the unwanted books, and importing new ones. If you are running different software you may have to make some minor changes.
Here are the steps that I took:
Removing the 100 Free Books:
I found some instructions online, that had some pretty straight forward and simple instructions for clearing out the SQL table that held the free book information. The problem is that the instructions were for the Mac OS. Since the Mac OS and Linux are pretty close, I was able to follow them fairly easily.
Please make sure that the Kobo is fully charged, and if possible plug-in the Kobo and back-up your /KOBOeReader/.kobo/KoboReader.sqlite file. This is the file that contains information about the 100% free books, and if something goes wrong, you may have to restore it.
1) Install SQLite3
Open a Terminal window and type:
# sudo apt-get install sqlite3
You will get a prompt asking you to type in your Root (sudo) password. Once you have properly authenticated you will see a bunch of information similar to the section below:
[sudo] password for Admin: ****

2) Use SQLite3 to modify the KoboReader.sqlite file to remove the 100 free books.
Plug-in the Kobo device, and when its mounted, open a Terminal window and type:
# sqlite3 /Volumes/KOBOeReader/.kobo/KoboReader.sqlite “delete from content where ___userid != ‘adobe_user'”
(Make sure to change the /Volumes/KOBOeReader/ path to match where the mount places the Kobo.)
3) Demount the Kobo volume and unplug the Kobo from the computer.
How to add (import) books to the Kobo device:
1) Plug-in the Kobo device to your computer.
2) Once the device is mounted, create a folder on the device for your books. I created one simply called “Imports”
3) Copy your EPUB formated books to the new folder.
4) Demount the Kobo volume and unplug the Kobo from the computer.
