Files that contain the .tst file extension are most commonly associated with the ExamView testing software. This program allows individuals to create tests for use in print, online or on the computer. The TST files that are use by the ExamView software contain the test files that have been created within the program.
The Pro/ENGINEER software application also uses the .tst file suffix. Pro/ENGINEER is a single database, parametric and modular process-oriented PLM system. The TST files that are used by the Pro/ENGINEER system contain temporary files that are created by the program during routine use. These files are normally deleted automatically once they are no longer needed.
