    Hidden from what or who? Are you referring to the windows file attribute?

    Yes. It is a sensitive file that I do not want to normal user to see.

    Perhaps SetFileAttributes will do what you want, although this is more of a Windows specific question.

    Sorry about the windows thing, I didn't know if there was a platform independent solution (which I would love). However, SetFileAttributes worked perfectly for me on windows. Unfortunately, the goal was to be as platform independent as possible (my GUI is using wxWidgets) but ah well.

    No. Let it stay here. Hopefully some moderator will move it. Regardless, if you need a platform independent solution, you have one with boost::filesystem
    The programmer’s wife tells him: “Run to the store and pick up a loaf of bread. If they have eggs, get a dozen.”
    The programmer comes home with 12 loaves of bread.

    Does boost::filesystem have something like a hidden attribute?

    Hmm... I honestly don't know. It lets you extract data like last modified date...
    But file attributes may be an entire different game.

    I don't think it does. The reason I didn't put this on Windows is that I am looking for a platform independent solution, not one that only works on Windows.

    Umm...as I just said my question was not supposed to be windows specific.

    So you end up with two small files in the corner of your whole project labelled
    horridWindowsHacks.c
    horridLinuxHacks.c

    Both provide an interface like
    myProtectFile ( const char *filename );

    The windows one implements it using SetFileAttributes
    The Linux one implements it using rename or chmod

    That is, you achieve the portability by concentrating all the non-portable code into as small a place as possible.



    > Does anyone know how to make a file hidden?
    Hidden from whom?
    If it's from yourself in normal file lists, then making it hidden on windows, or making the first letter of the filename a '.' on unix is one way to go.
    If it's from everyone else, then you need to set the read/write ownership to "user only". That would be chmod on unix, but I've no idea what windows would use.

    Are you setting the permissions before or after you've filled the file with sensitive information?
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    I would suggest encrypting it then. Perhaps both 'hide' it and encrypt it.
