Help software that can detect last acces

Hey guys,
Can anyone tell me of a software for Windows NT 4.0 that can tell me the last access date of a home drive. I work at a college for about the past year and a half and they have numerous home drives that are wasting space. Is there any software out there that will let me do this. I’ve already installed Quota Manager so this eliminated the problem for the future. Now it is time to clean up the past. Thanks all who reply.
