OK, I have ended with this code

#ifdef POSIX
void RealizeDirectory(String dir, int mode)
#else
void RealizeDirectory(String dir)
#endif
{
	Vector<String> p;
	while(dir.GetLength() > DIR_MIN) {
		p.Add(dir);
		dir = GetFileFolder(dir);
	}
	for(int i = p.GetCount() - 1; i >= 0; i--)
		if(!DirectoryExists(p[i]))
#ifdef POSIX
			DirectoryCreate(p[i], mode);
#else
			DirectoryCreate(p[i]);
#endif
}

This is definitely a step in the right direction Smile

Without NormalizePath function your code still not working with "a\b\c" directory. As stated in the comments:

#ifdef PLATFORM_WIN32
#define DIR_MIN 3 //!! wrong! what about \a\b\c ?
#endif

This is my intention.
It's not wrong with recursion, if they not too long for the stack overflow Wink

. I think it's not a problem (MAX_PATH == 260 in the stdlib.h).
So, you prefer:

dir.GetLength() > DIR_MIN

I use another more adequate method (in my opinion of course):

i>0 && path[i - 1] != ':'

To note:
- DirectoryCreate returns variable about success of directory creation. DirectoryCreateMulti do this also.
- DirectoryCreateMulti doesn't keep all directories for verification of existent directory. They use backward search with ReverseFind function.
