What is a TCX file?

Files with the .TCX contain fitness data encoded in the XML format and used for exchanging information between Garmin devices. The data can contain information such as the type of the undertaken sport, the measured times, the travelled distance, the burnt calories, and the intensity of the training.

Viewer can be used to view as text or hex any file of almost any size - up to millions of lines. It is designed to cope with DOS and UNIX type lines and includes search features and the ability to save as a text file any segment of the source file. The free TCX Converter application has been created to solve this kind of problems. Don’t let its name mislead you: TCX Converter is more than a simple conversion solution for TCX files. It can also load GPX, KML, TRK, FITLOG, FIT, PLT and CSV files and export to TCX, GPX, KML, PLT, HRM, TRK, CSV and FIT files.


TCX files in both of their forms can be opened using special software developed by Garmin called Training Center. The format is also supported by MotionBased.Com and the Garmin Communicator Plugin.

How to open TCX files

If you cannot open the TCX file on your computer - there may be several reasons. The first and most important reason (the most common) is the lack of a suitable software that supports TCX among those that are installed on your device.

A very simple way to solve this problem is to find and download the appropriate application. The first part of the task has already been done – the software supporting the TCX file can be found in the table. Now just download and install the appropriate application.

Possible problems with the TCX format files

The inability to open and operate the TCX file does not necessarily mean that you do not have an appropriate software installed on your computer. There may be other problems that also block our ability to operate the Garmin Training Center Database XML Format file. Below is a list of possible problems.

  • Corruption of a TCX file which is being opened
  • Incorrect links to the TCX file in registry entries.
  • Accidental deletion of the description of the TCX from the Windows registry
  • Incomplete installation of an application that supports the TCX format
  • The TCX file which is being opened is infected with an undesirable malware.
  • The computer does not have enough hardware resources to cope with the opening of the TCX file.
  • Drivers of equipment used by the computer to open a TCX file are out of date.

If you are sure that all of these reasons do not exist in your case (or have already been eliminated), the TCX file should operate with your programs without any problem. If the problem with the TCX file has not been solved, it may be due to the fact that in this case there is also another rare problem with the TCX file. In this case, the only you can do is to ask for assistance of a professional staff.

How to associate the file with an installed software?

If you want to associate a file with a new program (e.g. my-file.TCX) you have two ways to do it. The first and the easiest one is to right-click on the selected TCX file. From the drop-down menu select 'Choose default program', then click 'Browse' and find the desired program. The whole operation must be confirmed by clicking OK. The second and more difficult to do is associate the TCX file extension to the corresponding software in the Windows Registry.

Is there one way to open unknown files?

Tcx File Viewer

Many files contain only simple text data. It is possible that while opening unknown files (e.g. TCX) with a simple text editor like Windows Notepad will allow us to see some of the data encoded in the file. This method allows you to preview the contents of many files, but probably not in such a structure as a program dedicated to support them.
