No specific vendor, application, or operating system association is established for the .tt_ file extension.
Because the format is unknown, there is no reliable information about the data a .tt_ file contains or how it should be used.
No specific program can be recommended for opening a .tt_ file because the format is unidentified. The software that created the file, or the source from which it was obtained, may provide the necessary information.
Do not rename the file or open it in an unrelated application unless its origin is known, as this may not make the contents readable.
A .tt_ file cannot be converted reliably while its format and originating software are unknown. Conversion requires identifying the file first and then using an export or conversion function provided by compatible software.
