File with a .TLL extension contains user’s configuration of an LG TV, such as lists of TV channels, pre-defined start channel, default volume or its possible range.
TLL files can be transferred from a PC onto a TV and backward, via flash memory or a specific device, such as TLL-1100A TV Link Loader. They can be edited and custom-adjusted on a PC, if a specific software is provided.
