Creating an overview for orphaned (unused) files

This is just one of these things which makes you wonder how other people are handling this issue. The problem: when files are uploaded through IMCE (or via the insert module using an imagefield or filefield) there is no way to have an overview of all the files to see which ones are used (and in what nodes) and which ones are "left behind". This issue has been resolved in D7 using the media module but if you are stuck with a D6 site, the closes thing I found is this feature request in the auditfiles module issue queue.
