'My Documents' is shown as a Folder in Win7 since it is a Directory Link. In findfirst I want to be able to differentiate between a propoer Folder and a
Directory link. I use Delphi 2007 on Win7.

i can find the file with this code:
procedure TfrmTestEE.Button1Click(Sender: TObject);
var sr: TSearchRec;
  procedure AddFile;
    Memo1.Lines.Add(Format('%s : %x', [sr.Name, sr.Attr]));
  if FindFirst('c:\Users\Default\MYDOCU~1', faHidden + faSysFile + faSymLink + faDirectory, sr) = 0 then
    while FindNext(sr) = 0 do

Open in new window

My Documents : 2416

By checking the attributes i can see the symbolic link:
>  faHidden    = $00000002 platform;
> faSysFile   = $00000004 platform;
>  faDirectory = $00000010;

so far the parameters we know about ...
The 2 and 4 are in this list:
0400: ReparsePoint
2000: NotContentIndexed

So you are looking for files with attr: Attr and $0400 = $0400

{ File attribute constants }

  faReadOnly  = $00000001 platform;
  faHidden    = $00000002 platform;
  faSysFile   = $00000004 platform;
  faVolumeID  = $00000008 platform deprecated;  // not used in Win32
  faDirectory = $00000010;
  faArchive   = $00000020 platform;
  faSymLink   = $00000040 platform;
  faNormal    = $00000080 platform;
  faTemporary = $00000100 platform;
  faAnyFile   = $000001FF;
