File Extensions

These are all of the different file extensions that you can run across when accessing or transferring files. They are split up into the TI-83 category, the TI-83+ category, the TI-84+ C Silver Edition category, and the TI-84+CE category. You will probably notice that the main difference is that the 83* for the TI-83 was replaced with the 8X* for the TI-83+. The TI-83+ also has Flash ROM, so there are file extensions for that. The TI-84 + C Silver Edition has most of the same extensions, with the major difference being the .8CK (Flash App) and .8CU (OS). The same applies to the TI-84+CE with its extensions being .8EU (OS) and .8EK (Flash App).
