To add your dictionary to a Kobo reader (touch, Glo, Mini, Aura)
- Connect your Kobo to your PC.
- On the Kobo go to the ".kobo\dict" folder, and rename the dictionary you want to replace e.g. "dicthtml.zip" to "dicthtml.backup.zip". This backs up your existing English dictionary (if you skip this step no problem. You can refetch the settings by simply synchronising your Kobo)
- Copy the file you created with the dictionary creator (e-dict.exe) to the ".kobo\dict" folder on the reader.
- Eject and disconnect the Kobo. Sometimes it is neccessary to switch between the dictionary to force a reload of the newly created dictionary file on the reader.
- Enjoy!
