Notes about the TNO file extension:
To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened
" (Windows 7) or "How do you want to open this file?
" (Windows 10) if you double-click the file. There click on "More apps"
and choose a suitable software to view such files on your PC or from email attachments.
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.
