+### format
+
+Sets the format used when writing log entries to a file. `winget` is the default and uses the standard WinGet log format. `ccm` writes entries in a [CMTrace](https://learn.microsoft.com/mem/configmgr/core/support/cmtrace)-compatible format, which is useful when collecting winget logs alongside Configuration Manager (CCM) logs. Invalid values will revert to `winget`.

+
 ### file
 
 The `file` settings control the log files generated by winget during operation.  These settings apply to the automatic cleanup that happens whenever a Windows Package Manager process is run.
