I'm in need of a utility that is able to delete any or all files last
ACCESSED before a given date on a specified volume or path. We are
introducing a 3 year retention period.

Nice-to-have features would be:
ability to specify file extension
listing and confirmation before deletion.

Does anyone have any experience of such a utility? Would File System
Factory fit the bill? I do not currently have a test lab but could possibly
build a temporary one to test if I thought it would do the job.

Any suggestions welcome. Thanks.
