How to export highlights and annotations from Kobo eReaders

Open up D:\.kobo\Kobo\Kobo eReader.conf (where D: is the Kobo’s mount point) and add (or modify) the following block:

[FeatureSettings]
ExportHighlights=true

This should add a new menu option for a given book (accessible in My Books) allowing highlights and annotations to be extracted to the root of the Kobo mount.
