There's also a security issue: by default, the FTP protocol has no protection against password guessing and login attempts, so someone can simply try the available passwords to gain access to the folders. If someone intercepts your Wi-Fi traffic or connects to your local network, they will be able to intercept all this data and download it to themselves, in parallel with you.
