How to get a list of all subdirectories in the current folder

Answer:

Enumerating all folders in a subfolder/ directory:
1   
2   procedure EnumFolders(root: string; folders: TStrings);
3   
4     procedure Enum(dir: string);
5     var
6       SR: TSearchRec;
7       ret: Integer;
8     begin
9       if dir[length(dir)] <> '\' then
10        dir := dir + '\';
11      ret := FindFirst(dir + '*.*', faDirectory, SR);
12      if ret = 0 then
13      try
14        repeat
15          if ((SR.Attr and faDirectory) < > 0) and (SR.Name <> '.') and
16  						 (SR.Name <> '..') then
17          begin
18            folders.add(dir + SR.Name);
19            Enum(dir + SR.Name);
20          end;
21          ret := FindNext(SR);
22        until
23          ret <> 0;
24      finally
25        FindClose(SR)
26      end;
27    end;
28  
29  begin
30    Folders.Clear;
31    if root < > emptyStr then
32      Enum(root);
33  end;
34  
35  procedure TForm1.Button1Click(Sender: TObject);
36  begin
37    EnumFolders('C:\windows', memo1.lines);
38  end;
