How to clean Local Directory in FTP Inbound Channel Adapter

[guoxu1231]

Hi Guys,

I found FTP Inbound Channel Adapter is very useful to integrate legacy mainframe system cause they also write to FTP directly as a output.

Below is my configuration to polling remote FTP folder changes, once new files arrived, new message(File as a payload) will be generated to publish-subscribe-channel for later processing.

My requirement is pulling remote FTP folder, download to local directory, delete remote FTP files, process local file then archive to another folder.
But I found local-directory in FTP Inbound Channel Adapter is strange, I can not even delete them manually.

So my question is,
How to clean Local Directory in FTP Inbound Channel Adapter?

	<int-ftp:inbound-channel-adapter id="ftpAdapter"
		cache-sessions="false" channel="B-40-channel"
		session-factory="eFtpClientFactory" 
		auto-create-local-directory="true" delete-remote-files="true"
		remote-directory="${B-40-remoteDirectory}" local-directory="${B-40-localDirectory}"
		temporary-file-suffix=".trl">
		<int:poller max-messages-per-poll="-1" fixed-rate="${FTPPollingRate}" />
	</int-ftp:inbound-channel-adapter>

	<int:publish-subscribe-channel id="B-40-channel">
	</int:publish-subscribe-channel>

It seems it's a similar issue with INT-1843
