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

 // base case . . .if directory exists

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

 // actual work


  • I used MakeSureDirectoryPathExists successfully

  • A much more optimized method

    return 0;
