We have placed no limit on the number of TP4 files you can load to a device.

All TPControl Tokens, for multi-file supported devices, comes with 2 file slots as standard, and for each additional file-slot you require, you simply apply a TP4 File Slot KEY to the token in 'TPCloud -> Tokens -> (token) -> Settings and TP4 files', to unlock an extra file-slot.
