' For File.Exists, Directory.Exists
Imports System.IO
Imports System.Collections
Public Class RecursiveFileProcessor
Public Overloads Shared Sub Main(ByVal args() As String)
Dim path As String
For Each path In args
If File.Exists(path) Then
' This path is a file.

' Process all files in the directory passed in, recurse on any directories
' that are found, and process the files they contain.
Public Shared Sub ProcessDirectory(ByVal targetDirectory As String)
Dim fileEntries As String() = Directory.GetFiles(targetDirectory)
' Process the list of files found in the directory.
Dim fileName As String
