List of unused reports

[stefano@BL]

Hi all,
we have an installation of Cognos with hundreds of reports; now we would like to reorganize the areas and first of all remove the unused reports.
How can I get the list of unused reports in Cognos?
Thanks
stefano

If you have audit enabled, you can see which reports are being used with the audit extension package, a free download. I do not know if the content store tables have a "last used date" you could query.

Hi, thank you for your answer.
But with Audit package I can only see which reports are uses; what I need would be the reports that are never used, and if I understand well it doesn't give me this information
