    This is how you see it. I have not heard that there is any tool to help
    here.

    I would not call this fragmentation. It is more like spreading the files
    from one directory all over the disk.

    It might not affect stability but it increases the chances to fix a
    problem in case of a crash.

    I never thought of this.
