What is the TMC 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, ignore references to these TMC files.
The trace message control (.tmc) file is a text file that contains the control GUID along with the trace levels of each trace provider that is represented in a PDB symbol file. The name of the TMC file is the control GUID of the trace provider, followed by the .tmc file name extension.
