TRT is an extension given to files used by an application called Team Sports Scheduling System. It is a tool developed by Galactix Software that allows you to create schedules for sports competitions in all disciplines. The application works under the control of Microsoft Windows.

TRT are files used to store a report template. These are text files containing blocks of code delimited by <% and%> tags. Such a template in TRT format can be supported by JavaScript and VBScript.
