After the download tasks are set ready, you can turn off the computer, and the TS-431 will download as many HD videos as you want. With the QGet utility you can manage your download tasks on multiple Turbo NAS devices remotely on the local network or the Internet. You can also install HappyGet app to back up abundant online videos to your TS-431.
Dropbox-like file synchronization across computers and mobile devices
