13484	exists doesn't clear no_such_file_or_directory type of error codes	Alex Weiss <alexweiss86@…>	Beman Dawes	"Windows 10, MSVC 19.13.26128.

exists() fails when it successfully determines that a file doesn't exist (i.e. it sets the error code to ERROR_FILE_NOT_FOUND or throws in the throwing version). According to the reference and the tutorial example, that should not happen. 

Code example:
{{{
        boost::filesystem::path p(""c:\\filethatdoesntexist"");
	boost::system::error_code ec;
	bool doesExist = boost::filesystem::exists(p, ec);
	if (ec == boost::system::errc::no_such_file_or_directory) {
		std::cout << ""shouldn't happen!\n"";
	}
}}}

Note that for existing files, exists() works as expected.
