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

    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.

  • A much more optimized method

    if ( pszLastSlash )
    cTmp = *pszLastSlash;
    *pszLastSlash = '\0';

    // try again with one less dir

    CreateAllDirectories( pszDir );

    *pszLastSlash = cTmp;

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

    return 0;

  • why not to use the api...
