I'm trying to scan Windows Directories in a console program. But, it's not working. It finds all the files in the directory. However, there is the following text that shouldn't be there:(The following is the whole output)(The problem is those periods. It thinks those are files when they aren't.)

Searching for files... . .. main.cpp palfix.dev Makefile.win main.o palfix.exe Done! Press any key to continue . . .


int main(int argc, char *argv[])
{
    WIN32_FIND_DATA dat;
    HANDLE search;
    
    printf("Searching for files...\n");
    search=FindFirstFile("*.*",&dat);
    if(search==INVALID_HANDLE_VALUE || ERROR_NO_MORE_FILES==GetLastError())
    {
    printf("Error: %s\n",GetLastError());
    }
    printf("%s\n",dat.cFileName);
    while(FindNextFile(search,&dat))
    {
                 printf("%s\n",dat.cFileName);
    }
    
    FindClose(search);
    
    printf("Done!\n");
    
    system("PAUSE");
    return EXIT_SUCCESS;
}

Read the description. It allows you to filter the results.

...    while(FindNextFile(search,&dat))    {         if( dat.cFileName && dat.cFileName[0] != '.' )                 printf("%s\n",dat.cFileName);    }...

There are valid files than can have a dot as the first char of the filename.
Check explicitely for the two filename "." and "..".
Check for the attribute flag FILE_ATTRIBUTE_DIRECTORY if you only want files.

That worked.

bool IsRealFile(char *filename){         if(filename[0]=='.')return 0;          return 1;}

Wrong, files and directories CAN start with a period. The single 'dot' refers to the current directory, while the double 'dot' refers to its parent directory.

You may want to take a look at Boost.Filesystem for things like this.

Download a library just to handle directorys/filesystems...
I guess it would be nice if it would fit into the following:(Since the website says it's portable)

1. Does it work on Windows,(Win98-Vista)
Linux, MAC OSX, ect.

2. Does it work with POSIX? That is, does it work with homebrew dev for Nintendo DS, Gamecube?(Wii too when we can do Wii HB)
