Private Shared Function TraverseFoldersRecursive(ByVal root As [login to view URL], AddListFiles As List(Of String), AddListFolders As List(Of String), ByRef ByteSize As Long, Optional ByRef FileCount As Integer = 0, Optional ByRef FolderCount As Integer = 0) As Long Dim files As [login to view URL]() = Nothing Dim subDirs As [login to view URL]() = Nothing Try files = [login to view URL]("*.*") Catch End Try If files IsNot Nothing Then For Each fi As [login to view URL] In files '[login to view URL]([login to view URL]) [login to view URL]([login to view URL]) ByteSize += [login to view URL] FileCount += 1 Next subDirs = [login to view URL]() For Each dirInfo As [login to view URL] In subDirs [login to view URL]([login to view URL]) FolderCount += 1 TraverseFoldersRecursive(dirInfo, AddListFiles, AddListFolders, ByteSize, FileCount, FolderCount) Next End If Return ByteSize End Function
