the example list all folders under QTP installation folder. optionally you can load the output to an array, id you need to iterate the list.

Dim outMsg, listArr, dirName
dirname = Chr( 34 ) & Environment( "ProductDir" ) & Chr( 34 )
If Not RunDosCommand( "DIR /S " & dirname, outMsg ) Then
    Reporter.ReportEvent micFail, "RunDosCommand", outMsg
    ExitTest( "ERROR:RunDosCommand" )
End If
Print outMsg
' ** loading the list in an array
listArr = Split( outMsg, vbCrLf, -1 )

Note: When using Windows file names, you need to quote the path.

RunDosCommand Function

Public Function RunDosCommand( ByVal cmd, ByRef stdout )
   Dim sb, wShell, exec
   Dim input

   RunDosCommand = False
   Set wShell = CreateObject( "WScript.Shell" )
   ' ** Executing the command
   Set exec = wShell.Exec( "%comspec% /C " & cmd )
   ' ** Checking for errors...
   If Not exec.StdErr.AtEndOfStream Then
      stdout = "STDERR: " & exec.StdErr.ReadAll
      Set exec = Nothing : Set wShell = Nothing
      Exit Function
   End If
   ' ** The stringBuilder is faster than concatenation ( & )
   Set sb = DotNetFactory.CreateInstance( "System.Text.StringBuilder" )
   Do While Not exec.StdOut.AtEndOfStream
      input = Trim( exec.StdOut.ReadLine )
      ' ** Appending only not empty lines 
      If Len( input ) > 0 Then
         sb.AppendLine input
      End If
   Loop
   ' ** retieve the output
   stdout = sb.ToString
   RunDosCommand = True
   Set sb = Nothing : Set exec = Nothing : Set wShell = Nothing
End Function
