| Creates (makes) a directory. "dirname" specifies path of the directory to be created. Please note 
      that this function creates only ONE directory at a time. So if you want to 
      create nested directory tree you have to call it multiple times, for 
      example to create C:MyDirectoryMySubDirectory folder you have to call it 
      twice: 
       fmkdir( "C:\\MyDirectory" );fmkdir( 
      "C:\\MyDirectory\\MySubDirectory" );
 Note also that it is safe to call it even if directory already exists 
      (then no change to file system is applied) 
       Returns TRUE if directory successfully created, FALSE otherwise
