A TQS file is a program file created by Trivia Quiz Shell, a freeware application used by teachers and students to facilitate learning and test knowledge. It contains a learning program built by a user and is saved in XML format. TQS files may include multiple choice questions, true-false questions, fill-in-the-blank questions, hangman games, menus, embedded images, and sounds.

The TQS file is the main file type associated with Trivia Quiz Shell, which can be used to create and open the file. There are no other programs that can open the file. However, you can manually open the file as an .XML file to view its contents in XML format. Trivia Quiz Shell is primarily used for academic purposes. Both teachers and students use the program to learn material and test what they have learned. It can be used to create custom tests and report scores.
