A large backup file approx 15G successfully gets uploaded to a network drive which Boxcryptor encrypts. As soon as the file is uploaded and briefly shows the correct size it changes to zero bytes. I am then unable to test download it. It says 'Can't read from source file or disk.' There is nothing wrong with the drive or folder the file gets uploaded to. Creating an empty .txt file and then downloading it works fine.
Is there limitations on size?
