  • Hi,


    The SFC.exe program writes the details of each verification operation and of each repair operation to the CBS.log file. The CBS.persist.log is generated when the CBS gets to be around 50 meg in size. CBS.log is copied to cbs.persist.log and a new cbs.log file is started.


    It would be useful only for troubleshooting issues. If you are sure your system is running fine, you can delete this file. SFC.exe will create a new one, next time it is run.


    Hope this helps.
