TI Connect is Texas Instruments software for Microsoft Windows that manages data transfers between a computer and TI calculators and can create calculator backups.
A tig file contains calculator backup data for use with TI Connect. It is a program-specific backup format rather than a general-purpose document or data-exchange format.
Use TI Connect on Microsoft Windows to work with a tig file. Use the software's backup or restore functions to access the backup and transfer its contents to a compatible TI calculator.
A tig file normally cannot be converted meaningfully with a general file converter. To access individual calculator files, restore the backup with TI Connect and then transfer the required files separately.
