Forgive me if this is a stupid question, but with search I haven't found the answer, forum or google.
I've connected Kobo to my pc as an external device, copied my library folder, all works fine.
After that, I've installed Calibre and I've linked it successfully to my Library folder on pc. Download various Kobo plugins for conversion and other operations, all works well, device is recognized. When I send an epub, it results on the root of device, and not on my folder, but I'm not able to set the path as for Calibre Library.
Is there a way to do it?

Second question: I would like to add a column with format of book, but operation succeeds only on Calibre library, not for the Kobo (I don't see how to add the column).

Thank you for your patience.
