MOBI and EPUB files, but also PDF and even TXT files can be easily added to your Calibre library by dragging them to the application window. First of all, you will need to download Calibre by visiting the Calibre website.


Depending on the number of books this may take a while but you can monitor progress.

Choose Move library to a new location and select your local Onedrive folder. Start Calibre, click the Calibre button on the ribbon and choose Switch/create library.
