Plex is an incredibly interesting utility for movie fans. Through it, the NAS can stream multimedia content to a wide range of different devices.
While the Plex client application isn't free for Android and iOS devices, it is surely worth the money.
Dropbox
The Dropbox app provides a real-time synchronization service between its Dropbox folder on the NAS and the user's Dropbox files in the cloud. Please note that the NAS' Dropbox folder only supports up to 16 TB, so you will have to decrease its size if it is bigger.
Super Mario
This game is for all you Nintendo fans! We were surprised to find a game under the many available applications for this NAS, especially such a classic from the glory days of 8-bit console gaming.
