Description
The GetDirectories method returns an array of strings that hold the absolute paths of the sub-directories of the specified PathString. Optionally, this list may be limited by the Filter string.
 
The array size is dynamically set by this method.
 
This filter string may contain valid directory name characters, but may not have consecutive . characters. Use * wildcard to represent a sequence of 0 or more characters, and ? to represent a single character.

var
  BasePath : String;
  Folders  : Array of String;
  i        : Integer;

begin
  // Create a base folder
  BasePath := 'C:\Base';
  System.IO.Directory.CreateDirectory(BasePath);

  // And some sub-folders
  System.IO.Directory.CreateDirectory(BasePath+'\First');
  System.IO.Directory.CreateDirectory(BasePath+'\Second');
  System.IO.Directory.CreateDirectory(BasePath+'\Third');

  // List the folders under C:\Base
  Folders := System.IO.Directory.GetDirectories(BasePath);

  for i := 0 to Length(Folders)-1 do
    Console.WriteLine(Folders[i]);

  // Now delete this nest of folders
  System.IO.Directory.Delete(BasePath, true);

  Console.Readline;
end.
   C:\Base\First
   C:\Base\Second
   C:\Base\Third
Example of the second syntax

  // And some sub-folders
  System.IO.Directory.CreateDirectory(BasePath+'\First');
  System.IO.Directory.CreateDirectory(BasePath+'\Second');
  System.IO.Directory.CreateDirectory(BasePath+'\Third');

  // List the folders under C:\Base containing with 'r'
  Folders := System.IO.Directory.GetDirectories(BasePath, '*r*');

  for i := 0 to Length(Folders)-1 do
    Console.WriteLine(Folders[i]);

  // Now delete this nest of folders
  System.IO.Directory.Delete(BasePath, true);
