solr : How to Clear the baseDir folder after the DIH import - solr

Question

Solr Version :: 6.6.1
I am able to import the pdf files into the Solr system using the DIH and performs the indexing as expected. But i wish to clear the folder C:/solr-6.6.1/server/solr/core_K2_Depot/Depot after the successful finish of the indexing process.
Please suggest, if there is a way to delete all the files from the folder via the DIH data-config.xml or by another easier way.
<!--Local filesystem-->
<dataConfig>
<dataSource type="BinFileDataSource"/>
<document>
<entity name="K2FileEntity" processor="FileListEntityProcessor" dataSource="null"
recursive = "true"
baseDir="C:/solr-6.6.1/server/solr/core_K2_Depot/Depot" fileName=".*pdf" rootEntity="false">
<field column="file" name="id"/>
<field column="fileLastModified" name="lastmodified" />
<entity name="pdf" processor="TikaEntityProcessor" onError="skip"
url="${K2FileEntity.fileAbsolutePath}" format="text">
<field column="title" name="title" meta="true"/>
<field column="dc:format" name="format" meta="true"/>
<field column="text" name="text"/>
</entity>
</entity>
</document>
</dataConfig>

Usuaully, in production you want to run DIH proces via shell scripts, which are at first copying needed files for ftp, http, s3, etc, than runs full-import or delta-import and later track the status of the indexing via status command as soon as it will successfully ends you just need to execute rm command
while flag; do
curl -XGET // get status of the DIH
if finished change flag to false
rm files -rf // removing not needed files for indexing
There are no any support of deleting external files in Solr
