give a try to the Process class

Process.Start "del c:\YourFolder\*.foo"

See,7,10,,176 for more details on how to use the Process class.
Another way to do this if you want to have a little more internal control would be a function not unlike:

   Public Sub DeleteFiles(ByVal directory As String, ByVal extension As String)
      Dim filesToDelete As String()
      filesToDelete = System.IO.Directory.GetFiles(directory, "*." + extension)
      For Each thisFile As String In filesToDelete
   End Sub

Which you would call with:

   DeleteFiles("C:\Path\To\Directory", "xml")

This method goes to the specified directory, returns a list of all of the files within with the extension specified... and deletes each file one by one in a loop.
