Would you be able to print out what the values of message.size() and
fileSize are, right before you do that comparison?

Thanks.

Either I'm missing something, or...

file_size takes a path reference as its calling argument. You're passing
a string. How does this even compile?

Thanks for the Reply Rush.

If I modify the above code to contain the following I still see the same
behavior:
        const boost::filesystem::path filePath(fileName);
        const boost::intmax_t fileSize =
boost::filesystem::file_size(filePath);
