Can't find annotation files anymore

Hi there,

It used to be that I could find xml files of the highlights and annotations for my ebooks in a "digital editions" folder on my Kobo Glo. After some software update (not sure which), that folder seems to be missing. I've also turned on "show hidden files" to poke through all those folders, but nothing looks like my annotations.

Any idea on how to find these files nowadays? I know I can use the "fetch annotations" feature in Calibre, but that has been very incomplete the few times I've tried it so far.

Thanks!
