Hello
I'm primarily using Calibre when managing e-books on my tablet. But I have been wondering whether my purchased e-books are saved twice since I also have another e-book-programme on the tablet - each programme have a library with many of the same titles. Hopefully both programmes show the same file, but if that is not the case maybe I should delete the other programme. As far as I understand e-books are not very large files, but still it would be silly to use twice as much space.
