TOS 3.0.27 PART 1
I was actually somewhat surprised by the login screen of the TOS since i admit that i didn't expect something so nice looking and clean by a company like TerraMaster.
Things only got better once we entered the main screen since it looks a lot like Windows and some Linux versions.
From the upper right corner you can logout, change users, change the TOS theme, enter full screen and change the wallpaper while from the lower right corner you can check the current system status.
The top icon is the file manager which also resembles a lot the ones we find in Windows and Linux (even has thumbnail support).
TerraMaster currently has a limited number of compatible apps with the F2-220 and although not even close to what QNAP and ASUSTOR offer they can cover a wide range of uses.
From the privileges tab of the control panel you can add/remove users, create user groups and setup shared folders.
Moving to the network services tab you can check the current LAN status, enable file sharing, start the web server and virtual host and you can also enable UPNP discovery (only for devices that support UPNP).
Via the storage manager tab you can check the status of the installed drives, create/delete modes, configure ISCSI (connect the device with remote storage devices), enable/disable the virtual disk feature and check external connected drives.
