A TTC file may also be a configuration file used by TETR.IO to store user settings and preferences that control how the game behaves and appears, such as input settings, visual options, notifications, and other gameplay preferences.

More Information
TETR.IO is a free-to-play online multiplayer puzzle game inspired by classic Tetris. Players who want to fine-tune their gameplay experience, especially those who play competitively or prefer specific control schemes, are most likely to encounter TTC files. Advanced users may also share configuration files with others to replicate certain setups.
When TETR.IO loads a configuration, it reads the TTC file and applies the stored settings automatically. This ensures that user preferences, such as key bindings or display adjustments, are preserved without requiring manual setup each time.
