       Most Unix file systems, in their default mode, helpfully record when a
       file was last accessed. 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.
