Record marked as obsolete and not updated for a long time.
SunPinyin is an open-source Chinese input method that uses statistical language models to help convert phonetic input into Chinese characters. A t3g file stores data used by this language-processing system.
The file belongs to SunPinyin's internal data set and is used by the input method as part of its language model. Its contents are not normally meaningful as a standalone document.
The SunPinyin t3g format is considered obsolete and is no longer in common use.
Open a t3g file through the SunPinyin installation that uses it. The file is normally read automatically by SunPinyin and is not opened through a general-purpose document application.
Because the format is obsolete, current software may not recognize it. Do not modify the file manually if it is part of a SunPinyin data installation.
A t3g file is an internal SunPinyin language-model data file, so it has no practical document conversion or export path. It should be retained with the SunPinyin data set when compatibility with that installation is required.
