Make a big book fit.

A web novel with thousands of chapters is too long for Deckle to open today. Drop it here and it comes back in parts, each a book your X3 or X4 opens.

Choose a book or drop it here. An EPUB without DRM, or a .txt.

Then

Open the ZIP you downloaded.
Copy the parts to your card, anywhere on it. A folder of their own keeps them together.
In Books they show as a series, in order, and each says which chapters it holds.

It all happens in this browser: the book isn’t uploaded, and Deckle never sees it. Chapters stay whole and in order. A chapter too long to lay out is cut between paragraphs, with nothing added or lost.
