Dispose FileInfo()

 Dim FolderName As New IO.DirectoryInfo(FileLocationFolder)
 Dim diar1 As IO.FileInfo() = FolderName.GetFiles("*.xml")

I am looping through diar1 like the following

 For Each CurrFile In diar1
 Next 

Does that lock all the files in that directory?

If so, how do I dispose it after I am done? Any help would be appreciated.

Here is the rest of my code:

Public Sub Get_FTP_video(ByVal curr As Integer)
    Try

        Dim FolderName As New IO.DirectoryInfo(FileLocationFolder)
        Dim diar1 As IO.FileInfo() = FolderName.GetFiles("*.xml")

        Dim CurrFile As IO.FileInfo
        Dim CurrfileName As String
        Dim currsize, MinSize As Integer
        currsize = 0
        MinSize = 0

        For Each CurrFile In diar1
            CurrfileName = CurrFile.Name

            If CurrFile.CreationTime.Date = Today.Date Then
                GET_FileName(FileLocationFolder & CurrfileName, currsize)
                If MinSize = 0 Then
                    MinSize = currsize
                Else
                    If currsize < MinSize Then
                        splitter = CurrFile.Name.Split(".")
                        If My.Computer.FileSystem.FileExists(FileLocationFolder & splitter(0).ToString & ".mp4") Then
                            MinSize = currsize
                            newVideoName = splitter(0).ToString
                        End If
                    End If
                End If
            End If
        Next

        System.IO.File.Move(FileLocationFolder & videonamee & ".mp4", MoveFileToFolder & videonamee)
        sendmessage = True

        MoveAllFilesToBin()

The error occurs in this function:
