yes duhhud... that is exactly how yu do it with he T1 Plus.
Open My apps option from main screen and there you will find the File Browser.
Click it then you will see an option labeled as Store.
Open that and then you will see the USB devices connected and the SD Card should be shown there too.
If more then one USB drive is connected, they will both show there in that menu.
The T1 Plus will play almost any format, and if you have selected movies in different folders and you play one from inside that folder, then it will automatically switch to the next movie in that folder when the first movie is over.
Or if no folders and just a list on movies, then it will switch automatically too.
