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);
}
