There is only one file type that uses the .T2KS extension:
Teach2000 Exam Results File
Exam result file created by Teach2000, a memory trainer software; contains the results of a test taken by a student using the software; includes the student's score as well as which questions were answered correctly or incorrectly.
To take a test, a student receives access to a .T2KT file on a shared network location. After opening this file, he can take the test and the results are saved to a T2KS file. These exam results files are encrypted so that only the teacher can view the files for grading purposes.
