When I set up maxHistory in the XML file , for files deletion does not delete the files . I had my setup to keep 30 days of files , but did not work, and then I tried,for testing purposes with minutes and keeping 2 files but also did not work

This is the Minute XML config I set up

<appender name="FOLD_LOG_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
<File>/app/fold/logs/out.log</File>

<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<!-- rollover daily -->
<fileNamePattern>/app/fold/logs/out_%d

.txt</fileNamePattern>

<maxHistory>2</maxHistory>
</rollingPolicy>

<encoder>
<pattern>%d

[%thread] %-5level %logger

----- %msg%n</pattern>
</encoder>

</appender>
