Attached is a lisp file i use to use some time ago to save a copy of a file to be issued into an outgoing folder under the days date. It then binds the xrefs and removes any unreferenced xrefs. That said, it does not work properly and does seem to always bind all xrefs or remove unreferenced ones. Could someone please have a look to see if anything obvious. I know you will most say do a search, have done and tried a few, though most seem to never be perfect and work under all situations. not sure why that is?
