I'm using log4j2 for my app logs, I'm using XML and the configuration below is for the logs. I am storing logs in folders named after the current date. Every day a new folder is created with a name say '2018-11-15' and logs are stored into it. The code deletes the log files according to the size and age but does not delete the empty folders(2018-11-15) after these files are deleted from the folder.

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="warn" name="MyApp" packages="">
 <Properties>
 <Property name="baseDir">logs</Property>
 </Properties>
 <Appenders>
 <RollingFile name="RollingFile" fileName="$baseDir/app.log"
 filePattern="$baseDir/$$date:yyyy-MM/app-%dyyyy-MM-dd-HH-%i.log.gz">
 <PatternLayout pattern="%d %p %c1. [%t] %m%n" />
 <Policies>
 <TimeBasedTriggeringPolicy />
 <SizeBasedTriggeringPolicy size="250 MB"/>
 </Policies>
 <DefaultRolloverStrategy max="100">
 <!--
 Nested conditions: the inner condition is only evaluated on files
 for which the outer conditions are true.
 -->
 <Delete basePath="$baseDir" maxDepth="2">
 <IfFileName glob="*/app-*.log.gz">
 <IfLastModified age="30d">
 <IfAny>
 <IfAccumulatedFileSize exceeds="100 GB" />
 <IfAccumulatedFileCount exceeds="10" />
 </IfAny>
 </IfLastModified>
 </IfFileName>
 </Delete>
 </DefaultRolloverStrategy>
 </RollingFile>
 </Appenders>
 <Loggers>
 <Root level="error">
 <AppenderRef ref="RollingFile"/>
 </Root>
 </Loggers>
</Configuration>

How do I delete the folders once all the files inside it are deleted?
Thanx!

You don't have a build in option in log4j2 for deleting empty folders. You can check this StackOverflow answer, and this log4j2 issues discussion.

I would say the easiest way to handle this is to run a cron regardless to the log4j configuration. I use crontab.
