The following example shows how to show all files and their 
associated icons of a folder in a TListView. 
To test the code, you need a ListView1 and a ImageList1 where the icons are stored. 
}
 
uses  ShellApi;

procedure LV_InsertFiles(strPath: string; ListView: TListView; ImageList: TImageList);
var
  i: Integer;
  Icon: TIcon;
  SearchRec: TSearchRec;
  ListItem: TListItem;
  FileInfo: SHFILEINFO;
begin

  // Create a temporary TIcon 
Icon := TIcon.Create;
  ListView.Items.BeginUpdate;
  try
    // search for the first file 
   i := FindFirst(strPath + '*.*', faAnyFile, SearchRec);

    while i = 0 do
    begin
      with ListView do
      begin

        // On directories and volumes 
       if ((SearchRec.Attr and FaDirectory <> FaDirectory) and
          (SearchRec.Attr and FaVolumeId <> FaVolumeID)) then

        begin
          ListItem := ListView.Items.Add;

          //Get The DisplayName 
         SHGetFileInfo(PChar(strPath + SearchRec.Name), 0, FileInfo,
            SizeOf(FileInfo), SHGFI_DISPLAYNAME);
          Listitem.Caption := FileInfo.szDisplayName;

          // Get The TypeName 
         SHGetFileInfo(PChar(strPath + SearchRec.Name), 0, FileInfo,
           SizeOf(FileInfo), SHGFI_TYPENAME);
          ListItem.SubItems.Add(FileInfo.szTypeName);

          //Get The Icon That Represents The File 
         SHGetFileInfo(PChar(strPath + SearchRec.Name), 0, FileInfo,
            SizeOf(FileInfo), SHGFI_ICON or SHGFI_SMALLICON);
          icon.Handle := FileInfo.hIcon;
          ListItem.ImageIndex := ImageList.AddIcon(Icon);

          // Destroy the Icon 
         DestroyIcon(FileInfo.hIcon);
        end;
      end;
      i := FindNext(SearchRec);
    end;
  finally
    Icon.Free;
    ListView.Items.EndUpdate;
  end;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin

  // Assign a Imagelist to the ListView 
ListView1.SmallImages := ImageList1;

  // Show Listview in Report Style and add 2 Columns 
ListView1.ViewStyle := vsReport;
  ListView1.Columns.Add;
  ListView1.Columns.Add;
  LV_InsertFiles('C:\Windows\', ListView1, ImageList1);
end;

не будет проще?
