That's expected: a directory's file grows very slowly, since each entry takes up a small number of bytes, so another 4K block will be allocated only after lots of files are added. But that doesn't mean it's not an indication of a change. > In other words, it is useless for our purposes. I'm at a loss how you arrived at that conclusion, especially since I suggested looking at the size for the benefit of systems that cannot use the time stamp. Isn't this better than not knowing the directory changed at all?
