Notes about the TNO file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries
, unused processes and other unfavourable system settings to identify slowdown issues.
The TNO file type is primarily associated with 'TI-Nspire' by Texas Instruments Incorporated. TI-Nspire learning technology provides learning tools for pre-algebra through calculus and meets different classroom and curriculum needs. This is an operating system image for a TI-Nspire (non-Computer Algebra System) handheld graphing calculator.
