Question

I work in a project and I need to know if a file is unique in a directory or not.
So how can I find if a file exists in a directory or not?
I have the file name without extension and the path of the directory.

There’s no ready-made function for this I think, but you can use something like this:

static bool fileExists( const char *path )
{
    const DWORD attr = ::GetFileAttributesA( path );
    return attr != INVALID_FILE_ATTRIBUTES &&
           ( ( attr & FILE_ATTRIBUTE_ARCHIVE ) || ( attr & FILE_ATTRIBUTE_NORMAL ) );
}

This verifies that it’s a “normal” file. You might want to add/remove flag checks if you want to deal with hidden files, too.
