NLog - It doesn't delete old log files

Question

ASP.NET CORE Using NLog

I have some trouble , it doesn't delete old logs file.

"MaxArchiveFiles" and "maxArchiveDays" did not execute the action of deleting logs properly.

What I do wrong? Thanks!

Current files (files from today) are not part of archive when using MaxArchiveDays. So maxArchiveDays="1" will only clean files older than yesterday.

You could consider removing archiveFileName and archiveDateFormat and archiveNumbering , so it becomes this:

    <target xsi:type="File" name="ALL"
            fileName="C:\Logs\testProject\testProject.${cached:${date:format=yyyy-MM-dd}}.log"
            layout="${longdate}|${uppercase:${level}}|${threadid}|${logger}|${message} ${exception:format=ToString}"
            maxArchiveFiles="100"
            archiveAboveSize="10485760"
            maxArchiveDays="1"
          />
