What is the .TEC File Extension?

.TEC File Extension Description:

Tecplot uses Files saved with the .tec file extension. Tecplot is a software tool used to create and save a TEC graphics file with the TEC file extension. The Tecplot software contains macro commands that can be used by users to accomplish tasks with ease; this can automate redundant tasks in Tecplot. Some of the macro commands available within Tecplot do not have any control requiring interaction. This is useful for loop required commands. All of these macros are available files in the .tec file extension.

When creating or editing data within a file with the .tec file extension, a workspace is made available via the Tecplot interface. In here, a portion of the screen is used as a preview, where sketches and plots are created. These are all seen inside a frame, where data is manipulated like a process window. The workspace, the size and positions of frames, the data files' location per frame, and all attributes currently used for the project are stored on the layout.

When writing out data onto files with the .tec file extension, they can be encoded either in ASCII, or in raw binary format. The Tecplot software will prompt users what part of data to write and what type of output format is generated. Data sets in the TEC file extension are assigned to frames, which can also be assigned to zones (this is useful when managing multiple projects all at the same time). The Tecplot interface will group the zones from projects and show them in the data set. Ideally, all the zones in the file have variables defined for the data sets.

Files of the .tec files extension were also used by an old editor called TECO that is not well-equipped for today's environment; The TECO editor still has some advantages over the newer editors. The TEC file extension contains embedded macro libraries, which make it very usable. Some options that sets TEC file extensions apart, is its ability to store any file size, run complex repetitions and loops, and use expressions and conditional operands for execution.
