Open TET File

A TET file could refer to a TestExecute Test or a TetGen Input Geometry file. Each of these files is used by a different type of software and is opened differently.

TetGen Input Geometry Files

TetGen is software for producing high quality tetrahedral meshes suitable for numerical simulation. If your file is a TetGen Input Geometry file, it was most likely created by a science or engineering professional using TetGen. You can also open it using the TetGen software, which is free and open source.

TestExecute Test Files

The TestExecute Test file format is quite different from TetGen. These files are created by TestExecute software, which is a product by SmartBear that automates routine application testing.

Opening a TET file

For both TetGen Input Geometry and TestExecute Test files, it is easiest to use the software that created them. If you are not sure, you can try opening the file with a text editor like Notepad++ or Sublime Text. If the information within the file is readable, then it is a text-based file. If it's seemingly random characters, the file might be binary.
Do bear in mind, trying to open a TET file with the wrong software could corrupt the file.

TET File Important Information

If you're unable to open a TET file, it's often because you don't have the correct software installed on your system. It's important to remember that not all TET files are the same, and different TET files may require different software. Be sure to verify the type of TET file you're dealing with and to use the appropriate software. Software providers will often offer free trials, so this may help as a temporary solution.
