Hello, I visited the site about the installation of the metro for almost a year, but it was not as good as this one, but it has problems and it is still not complete. I hope that this movie will solve some problems.

...get the number of Files in the Recycle Bin and their total size?

	 	  
type
  PSHQueryRBInfo = ^TSHQueryRBInfo;
  TSHQueryRBInfo = packed record
    cbSize: DWORD;
    // Size of the structure, in bytes.
    // This member must be filled in prior to calling the function.
    i64Size: Int64;
    // Total size of all the objects in the specified Recycle Bin, in bytes.
    i64NumItems: Int64;
    // Total number of items in the specified Recycle Bin.
  end;

const
  shell32 = 'shell32.dll';

function SHQueryRecycleBin(szRootPath: PChar; SHQueryRBInfo: PSHQueryRBInfo): HResult;
  stdcall; external shell32 Name 'SHQueryRecycleBinA';

function GetDllVersion(FileName: string): Integer;
var
  InfoSize, Wnd: DWORD;
  VerBuf: Pointer;
  FI: PVSFixedFileInfo;
  VerSize: DWORD;
begin
  Result   := 0;
  InfoSize := GetFileVersionInfoSize(PChar(FileName), Wnd);
  if InfoSize <> 0 then
  begin
    GetMem(VerBuf, InfoSize);
    try
      if GetFileVersionInfo(PChar(FileName), Wnd, InfoSize, VerBuf) then
        if VerQueryValue(VerBuf, '\', Pointer(FI), VerSize) then
          Result := FI.dwFileVersionMS;
    finally
      FreeMem(VerBuf);
    end;
  end;
end;

procedure TForm1.Button1Click(Sender: TObject);
var
  DllVersion: integer;
  SHQueryRBInfo: TSHQueryRBInfo;
  r: HResult;
begin
  DllVersion := GetDllVersion(PChar(shell32));
  if DllVersion >= $00040048 then
  begin
    FillChar(SHQueryRBInfo, SizeOf(TSHQueryRBInfo), #0);
    SHQueryRBInfo.cbSize := SizeOf(TSHQueryRBInfo);
    R := SHQueryRecycleBin(nil, @SHQueryRBInfo);
    if r = s_OK then
    begin
      label1.Caption := Format('Size:%d Items:%d',
        [SHQueryRBInfo.i64Size, SHQueryRBInfo.i64NumItems]);
    end
    else
      label1.Caption := Format('Err:%x', [r]);
  end;
end;

The SHQueryRecycleBin API used in this method is
only available on systems with the latest shell32.dll installed with IE4 /
Active Desktop.
