Notes:
- Calibre Sync is not a reader app. You must install and use one of the many excellent reader apps available.
- Only Microsoft OneDrive for Personal accounts (shared) are supported. Please email us if you observe any inconsistencies.
- Due to restriction in Box API, Calibre Sync must acquire write permission in order to download files, download is not a read action on Box. Calibre Sync guarantees that it will not perform any write actions against your data in Box cloud account.
- Calibre Sync use WebDav API of Nextcloud and OwnCloud services, and it requires case sensitive file system to work properly. Therefore, you must make sure that your libraries are set up on case sensitive file system (Linux, recent MacOS, Windows NTFS with case sensitive enabled).

v6.10.4

Grundsätzlich ist es eine hervorragende App mit vielen praktischen Möglichkeiten. Einen gravierenden Nachteil hat sie allerdings: Will man nicht nur einzelne, sondern viele Bücher herunterladen - egal ob vom Calibre Inhalteserver oder aus der Cloud - dann geht das absolut unvorstellbar langsam. Bei einer Bibliothek mit mehreren tausend Büchern reden wir nicht von Stunden, sondern von Tagen... Wenn dieser Mangel behoben wird, gibt es sofort fünf Sterne.
