Geometric data is stored, but the user can also store associated quantities such as pressure, temperature, or velocity.

No compression (except for the binary data format option).

2D or 3D data, and can have time dependence.

Color is not associated with the data, but can be added during postprocessing by the TECPLOT program, or by associating variables 'R', 'G' and 'B' with data, for instance.

ASCII (although TECPLOT can create and use binary data files).

Tecplot tec files have the following characteristic: They can also be loaded directly to Tecplot and exported to another format. These files can be converted to standard binary PLT format used by TecPlot with preplot.exe program located in the /bin folder inside the program folder. Tecplot can probably work with them if the file extension is renamed back to dat. The more common and default file extension is dat, but some programs export Tecplot compatible data files with tec file extension instead. Tecplot, a a family of visualization software tools developed by Tecplot, Inc. File extension tec is sometimes used for Tecplot ASCII Data files.
