What is a T02 file?

T02 files mostly belong to Topcon Tools. The T02 file is a specialized data file. Its most common use is to store GPS data collected by surveying tools. In this form, the file contains geospatial coordinates, sensor readings, and other measurements meant for precise location mapping. It is typically used with Topcon Tools. For more details, see Topcon Positioning.
Other Uses:

Tax Return Data: Some applications use the T02 extension to store tax return information. These files are produced by products such as TaxAct and TurboTax. More details about TurboTax can be found at TurboTax.

Invoice Documents: A few T02 files follow the TIFF format to serve as containers for invoice images or IRS-related tax return data.

FilExt.com note: The file’s functionality depends on its origin. Opening a GPS-data T02 file with tax software (or vice versa) may not work correctly.
