This tip works with Windows 2000 (NTFS 5) and later
These 2 functions are defined in windows.pas, but they're defined wrong. In this
case our own definition.

function DecryptFile(lpFilename: PChar; dwReserved: DWORD): BOOL; stdcall;
external advapi32 name 'DecryptFileA';

if not EncryptFile('c:\temp') then
ShowMessage('Can''t encrypt directory.');
end;
procedure TForm1.Button2Click(Sender: TObject);

if not DecryptFile('c:\temp', 0) then
