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);

}
