What is a TRK file?
A .TRK file is a track data file. Because .TRK is a common file extension, it is used by several different software programs for entirely different purposes. A .TRK file can store DJ track references, GPS route coordinates, flight simulator replays, or physics analysis data.
Common TRK Formats
There are several popular formats that use the .TRK extension:
- Beatport Track File: Used by Beatport DJ to store track reference data.
- Flight Simulator Replays: Used by games like DCS World (Digital Combat Simulator) to save flight recordings. These are often formatted as compressed ZIP archives.
- GPS Track Log Files: Used by mapping applications like AlpineQuest and Garmin. A notable example is the CompeGPS Land Track File created by the CompeGPS TEAM for the CompeGPS TwoNav software.
- Tracker Video Analysis File: Used by the Open Source Physics Tracker to model video data. These are typically XML files.
- Medical Data: Used by the TrackVis visualization tool to store brain fiber tractography data.
How to open TRK files?
Opening a .TRK file depends entirely on the software that created it. If the file is a GPS track, you can open it in mapping software or use a command-line tool like GPSBabel to convert it into a standard .GPX file. If it is a DCS World replay, you must place the file in the game's replay folder. Because there are many types of .TRK files, you need to know the creator software first.
