Creating Mulitple Levels of Directories

I was writing a custom installation script and needed to create many sub directories. I looked at Brad Gutilla's article and thought that there had to be a simpler method. Recursion steps in and saves the day. Not much to say about the code, as it is pretty simple and easy to follow.
void CreateAllDirectories(CString strDir)
{
 // remove ending / if exists
 if(strDir.Right(1)=="\\")
  strDir=strDir.Left(strDir.GetLength()-1); 

 // base case . . .if directory exists
 if(GetFileAttributes(strDir)!=-1) 
  return;

 // recursive call, one less directory
 int nFound = strDir.ReverseFind('\\');
 CreateAllDirectories(strDir.Left(nFound)); 

 // actual work
 CreateDirectory(strDir,NULL); 
}

    So, I used MakeSureDirectoryPathExists from Imagehlp.h (instead of Dbghelp.h - I don't know where may I find this file). Do not forget to add to your project also Imagehlp.lib.

    if ( _mkdir( pszDir ) == -1 )
    {
    return -1;
    }

    return 0;
    }
