Remove File Tagged as Duplicate in SFTP server

Hello experts,

We have SFTP to Proxy scenarios in which all files in the SFTP server and checked for duplicate. What is required now is to remove the files tagged as duplicate in source directory. As you may already know the option available for sender SFTP adapter has no setting to move or transfer to another directory. We do not want duplicate files just be stuck on the source.

Any ideas? Thank you.
