Оформил: DeeCo

{ 
  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. 

  Im folgenden Beispiel werden alle Dateien & zugehorigen 
  Icons eines Verzeichnisses in einer TListView angezeigt. 
  Um das Beispiel zu testen, braucht man eine ListView1 und eine ImageList1 
  Komponente, wo die Icons gespeichert werden.
