You need an Autoindex job and a Deletion policy. Add a field to the file cabinet called "Duplicate".
Configure the Autoindex job to find the duplicates but set it to process only the First found document. Write the word "Duplicate" in to the Duplicate field for the first document. Also be sure to filter this job so that it selects only documents where the field "Duplicate" is empty.
Run the job and check carefully that the word Duplicate is only written to one of the duplicate documents. If this is true then configure a Deletion policy to delete documents where the word "Duplicate" is in the Duplicate field.
As I said, run the AIX job and be sure that it only flags the first document.
