The 8cg file extension is associated with the TI-84 Plus, a programmable graphing calculator developed by Texas Instruments and based on a Zilog Z80 processor.
An 8cg file contains a group of files or other data intended for the TI-84 Plus. Grouping allows several calculator items to be transferred or managed together rather than as separate files.
The format is used with Texas Instruments calculator-management software, including TI Connect for Microsoft Windows and TiLP on multiple platforms.
Open an 8cg file with TI Connect on Microsoft Windows or with TiLP on a supported platform. These programs can manage the grouped calculator data and transfer it to a connected TI-84 Plus calculator.
An 8cg file is a calculator group file, so it normally has no useful conversion to a general-purpose format. Use TI Connect or TiLP to transfer the group to a TI-84 Plus or to manage its individual calculator items where supported.
