- 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).
