In most cases where you have developed a on-premise applikasjon (console, service) these generates logfiles. Either for debugging purpose, or for validating the day-to-day execution wether there are errors or warning.
I tend to use text files, where I keep them for at least 14 days. The following command will delete all files older than 14 days from the c:\temp\logging folder. I have this at the top of my startup.cmd script.
rem delete files older than 14 days forfiles /p "C:\temp\Logging" /m "*.*" /c "cmd /c del @path" /D -14
