File Manager

Plug the reader in by USB and leave it on its Home screen.

Works in Chrome or Edge. The reader only accepts changes while it's on its Home screen.
Drag items onto a folder or a folder name in the path to move them; drop files from your computer to upload.
Moving or renaming a book keeps its reading stats (firmware v1.3.0+). Deleting a book doesn't delete its stats.
Uploading a file with the same name as one already there replaces it and keeps that book's stats.
