If the device is connected when doing this, it will be removed from the device immediately.
But doesn't that remove the books from the library altogether, without archiving them? (At installation the desktop app popped up a message about archiving, but I don't see that option anywhere in the programme.) I would like to keep the books in the cloud, in the library, just as an extra backup in case I ever lost all other copies and had to redownload it.
