How do I show all folders and files in drives C, D, or E in Delphi by using ListView-like control/component?

Question

How can I implement the idea in the pictures in a Delphi project? So that there is a TComboBox to display drives C, D and E with icons, and when choosing a path, all folders and files with icons appear at the bottom. I think it is TListview, so that when I click on a path, its files appear, and when I click on any file, any of its content appear, whether other files or images.

Those are legacy controls from 16 bit Windows 3.1 - you can find the controls in the tab "Win 3.1". They are:

• TDriveComboBox,
• TDirectoryListBox and
• TFileListBox

...all sitting in the Vcl.FileCtrl.pas unit.

In the properties you have to link each control to the other, so they automatically work together. Here's an example DFM as text, also with a TFilterComboBox:

object Form1: TForm1
  object dcbDrive: TDriveComboBox
    DirList = dlbFolder
  end
  object dlbFolder: TDirectoryListBox
    FileList = flbFile
  end
  object flbFile: TFileListBox
  end
  object fcbFilter: TFilterComboBox
    FileList = flbFile
  end
end
