A common use for such files is storing alternate covers or supplementary material associated with the book,” said Kovid Goyal. The data files are simple files stored in the data sub-folder inside the book’s folder.

“You can also manage the data files by right-clicking the Edit metadata button and choosing Manage data files. Users can add additional data files to a book by selecting the book, right-clicking the “Add books” button, and choosing the “Add data files to selected book records” option. However, this feature may not work on Linux systems, as stated by Kovid Goyal, due to challenges with proprietary codecs.Ī long-awaited feature in the new Calibre release is the capacity to store “data” files linked with a book and a built-in function to manage these files.

These notes can be searched, linked within the application or exported as independent HTML files by users.Īn intriguing addition in Calibre 7.0 is support for “Audio EPUB” books, which feature a voice reading the text. More than a year after Calibre 6.0, Calibre 7.0 comes with the functionality to save notes, which include links, images and rich text formating for authors, series, publishers, tags, and their related elements. Calibre’s developer Kovid Goyal publicized the release of Calibre 7.0, the most recent stable version and a significant update to this potent, open-source, and cross-platform e-book management software.
