    Re: mapped files

    They tend to be fastest, particularly when you have a very large file.
    They let you work the standard pointers, instead of file read & write fucntions.
    Any function that works with chr* (strlen, STL etc) can work directly on the file.

    Truth,

    I don't do it for the points (OK, maybe I do), but rating a post is a good way for me to know if I helped.
