title: Can we set unlimited maxFiles in winston?
body: <p>we have implemented logic using nodejs if existing file in directory more than 30 days delete the file so we dont want to winston set <code>maxFiles</code> because we want to keep files based on time .</p>
  
  <p>My second question related to winston is when we rotate file currently its appending server1.log once it reach file size , is it possible to append with date e.g <code>server-03-10-2017.log</code> ?</p>
  
  <p>ctrl.js</p>
  
  <pre><code>   var logger = new(winston.Logger)({
        level: null,
        transports: [
  //          new(winston.transports.Console)({formatter}),
            new(winston.transports.File)({
              filename: './logs/dit/server.log',
              maxsize: 1024 * 1024 * 20, // 15MB
              timestamp: true,
              maxFiles: 10,
              json: false,
              formatter: function (options) {
               return options.message;
              }
          })
      ]
  });
  </code></pre>
