Hola, a ver si te sirve esto:

Código Delphi [-]
unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls, ShFolder, ShlObj;

type
  TForm1 = class(TForm)
    Edit1: TEdit;
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.Button1Click(Sender: TObject);
const
  SHGFP_TYPE_CURRENT = 0;
var
  Buffer: array[0..MAX_PATH] of Char;begin
  SHGetFolderPath(0, CSIDL_PERSONAL, 0, SHGFP_TYPE_CURRENT, Buffer); //CSIDL_PERSONAL = es la variable que indica que carpeta queremos obtener
  Edit1.Text := Buffer;
end;

end.

Espero te sirva,

Saludos
