Identifiers
Well over 100 different filename extensions are used. In general, the first two characters of the extension indicate the calculator model, and the third character indicates the data type. For example, .89p is a Program in TI-89 format.
Identification
TI variable files begin with an 8 byte ASCII signature that starts with "**TI" and indicates the version or model, for example "**TI92**" or "**TI83F*". The next two or three bytes may also be considered to be part of the file signature, depending on the version.
