Save information about who deleted the attached file

Does anyone have any idea or routine that can store the information about who deleted an attached file from EPICOR?

Could you do a method directive on the delete method and log the metadata somewhere?

There is an audit log in ECM if they are there.

As Greg mentioned, are you wanting to know who deleted the reference in Epicor or the file itself? If the latter then that depends on where the file is stored.
