Trace Message Control File
Note Before Windows Vista, this type of file was generated by default by Tracepdb. Instead, the Tracepdb tool now generates a MOF (.mof) file that describes the provider information in the binary.
Unless you are using TraceView, you should ignore references to these TMC files.
A trace message control (TMC) file is a text file that contains the control GUID for each trace provider represented in a PDB file. The name of the TMC file is the control GUID of the trace provider, followed by the .tmc file name extension.
Tracefmt and TraceView create a TMC file for each trace provider when they create a trace message format (.tmf) file from the formatting instructions in a PDB file. Tracepdb can also generate a TMC file when you use the -c option.
The TMC file also contains the following information:
The path and file name of the PDB file.
The date and time that the PDB file was created.
The control GUID for each trace provider.
The trace flags defined by the trace provider.
TraceView uses the TMC file to find the trace flags for each provider. You can use this file as a quick reference to the control GUID of a trace provider.
