The 8ek file extension is used for data associated with the TI-84 Plus, a programmable graphing calculator developed by Texas Instruments in 2004. The calculator uses a Zilog Z80 processor.
An 8ek file contains data used by the TI-84 Plus. It is intended for use with the calculator rather than as a general-purpose document for desktop applications.
TI Connect can manage files for compatible Texas Instruments calculators and transfer them between a Windows computer and a connected TI-84 Plus. The 8ek format is a calculator-specific data format.
On Microsoft Windows, open the file with TI Connect if the file needs to be transferred to or managed with a TI-84 Plus. Connect the calculator to the computer and use TI Connect's file-transfer tools.
An 8ek file may not display meaningful content when opened as a regular document because it stores calculator data.
