I'm not sure whether it's a regular occurrence that ADE Annotations and Manifest directory/files shows up on a Glo that doesn't use wifi, and only has Calibre cleaned and side loaded ebooks, and is not ADE authorised .....
Yesterday I signed out of one account on the glo and then used a newly downloaded version of Kobo Desktop for PC to install the Glo firmware. I then side loaded the epubs from Calibre.
When I noticed the files I deleted .adobe-digital-editions directory, and the Digital Editions directory containing the files Annotations and Manifest, with no harm done because I was able to continue reading the book that was in the Manifest. The Manifest file appeared to copy the book from the book list into it.
But the next time that I plugged the Glo into the PC I noticed that these directories/files are back, and the book is back in the Manifest.
Is that normal?
Below are the pics.
