So if you generated a large amount of data years ago, forgot to clean it up, and have never used it since, then it ought in principle to be possible to use those last-access time stamps to tell the difference between that and a large amount of data you're still using regularly. agedu uses this information to tell you which files waste disk space when you haven't used them since a long time.
