In the "Core\Path.h" file we have useful function RealizeDirectory that creates not existent directories from the given path. I create alternative function with name DirectoryCreateMulti. Complexity: recursion versus memory management with Vector.

#ifdef PLATFORM_POSIX
bool DirectoryCreateMulti(const String& path, int mode = 0755)
#else
bool DirectoryCreateMulti(const String& path)
#endif
{
	Vector<String> dirs;
	
	for (int i=path.GetCount() - 1; ; --i)
	{
		i = path.ReverseFind(DIR_SEP, i);
#ifdef PLATFORM_POSIX
		if (i>0)
#else
		if (i>0 && path[i - 1] != ':')
#endif
		{
			const String tmp(path.Left(i));
			if (!DirectoryExists(tmp))
			{
				dirs.Add(tmp);
			}
			else break;
		}
		else break;
	}
	
	for (int i=dirs.GetCount() - 1; i>=0; --i)
	{
#ifdef PLATFORM_POSIX
		if (!DirectoryCreate(dirs[i], mode))
#else
		if (!DirectoryCreate(dirs[i]))
#endif
		{
			return false;
		}
	}
#ifdef PLATFORM_POSIX
	return DirectoryCreate(path, mode);
#else
	return DirectoryCreate(path);
#endif
}
