What is an .TMH file?

The trace message header (TMH) file is a text file that contains declarations of functions and variables used by the tracing code that WPP generates. The header file also includes macros that add trace message formatting instructions to a PDB file of a trace provider, such as a kernel-mode driver or user-mode application.

WPP generates the tmh file automatically when you compile a trace provider that includes WPP macros. The thm file has the same name as the source file, but with a .tmh file name extension. WPP saves the file in the same directory as the source file.

How to open:

Use Microsoft Windows Software Development Kit to open *.tmh header files.

How to convert:

Although you can technically "convert" message headers much like any other text file, there is practically no reason to do it, as such conversions would be pointless.

How to solve problems with TMH files

Associate the TMH file extension with the correct application. On :
Windows: Right click on any TMH file and then click "Open with" > "Choose another app". Now select another program and check the box "Always use this app to open *.TMH files". Mac: Right click (or Ctrl-click) the TMH file, then click "Open with" > "Other...". Then choose another program and check the "Always Open With" box. Linux: Right click on the file, and select "Open with" and choose another program. iPhone: Tap the file. If you do not see an app to open the file, then tap Share "Share" and choose an app. Alternatively, save the file. Then open the Files app Files app. There long-press on the file, then release your finger. You will see a black menu bar. Then tap "Share" and select an app. Android: Tap the Settings icon on your smartphone, then tap on the Apps section. There tap the Options icon in the top right-hand corner of the screen to change the default apps.
Update your software that should actually open .TMH is Trace message header. Because only the current version supports the latest TMH file format. Search, therefore, e.g. on the Microsoft Corporation manufacturer website after an available .TMH is Trace message header update.
To make sure that your TMH file is not corrupted or virus-infected, get the file again and scan it with antivirus software.
