The 89q file extension is associated with TI Connect, software from Texas Instruments for connecting compatible graphing calculators to a Microsoft Windows computer.
An 89q file stores certificate data used with a TI-89 Titanium calculator. The certificate is transferred to the calculator through TI Connect rather than opened as a document.
The format is intended for use with TI Connect and is not a general-purpose data format.
Open the 89q file with TI Connect on Microsoft Windows. Connect the compatible calculator to the computer, then use TI Connect to transfer the certificate to it.
The file is not intended to be viewed as readable text in a regular document application.
An 89q file is certificate data and cannot be meaningfully converted to a common document or image format.
Use TI Connect to transfer the certificate to a compatible calculator instead of converting the file.
